Whilst a vast number of studies have been conducted to investigate body odour and mating, research is now shifting in particular towards the effect of male scent to female sexual attraction. This is largely due to the effects of the menstrual cycle and hormone contraceptives , which directly affect women's partner preference. Past research has highlighted the importance of a male's scent to females, such that smell was rated significantly more important for women than men.
Furthermore, smell and body odour were rated as the most important physical factor for females, compared to looks for men. Using questionnaires and self-report data, a greater reliance was found for females on olfactory cues than males. This reliance was valued for females in both sexual and non-sexual contexts. It has been established that women tend to rely more heavily on olfactory cues than males, rating those with pleasant body odour as more attractive than those with less pleasant body odour.
Moreover, body odour and sexual attraction can be enhanced using artificial fragrances and dietary habits. Whilst males are influenced by body odour during selection, past research has demonstrated a significantly greater reliance on such cues by females. A dependence on such olfactory cues has led to the enhancement of male body odour to influence female attraction. Past research has shown that videos of men using fragranced antiperspirants were rated as more attractive by women than those in a placebo control condition.
In addition to this, females gave higher ratings of masculinity than males, particularly in the fragranced condition. Aside from artificial fragrances, researchers have also begun to focus on more natural odour enhancements such as diet quality. A recent study aimed to investigate whether a dietary fruit and vegetable intake would influence female mate preferences. Its results showed that subjects rated as most pleasant smelling were those with a higher fruit and vegetable intake, suggesting male body odour can be enhanced by diet to appeal to females.
Both sexes commonly use artificial scents to enhance their perceived sexual appeal. Many of these musk compounds share a similar chemical profile with naturally produced body chemicals. However, several infertility issues may arise when people use perfumes or scented body washes that erase their natural scent, hindering women in particular from being able to detect if their partner is genetically comparable.
Insects use extremely sensitive receptors to detect pheromone signals. Each pheromone signal can elicit a distinct response based on the gender and social status of the recipient. Insect sex pheromones, usually released by the female to lure a male, are vital in the process by which insects locate each other for mating.
Generally, the majority of insects are sensitive and selective to the sex pheromone of their own species. There is a significant amount of research supporting body odour and sexual attraction in insects. Observations and laboratory experiments of Culiseta inornata , identified a chemical substance involved in mating behavior, when exposed to this scent the male mosquitos were found to attempt sex with dead females and when exposed to the scent of virgin females, the males showed increased sexual activity through excited flight, searching and attempts to copulate with other males.
For vertebrates, aquatic environments are an ideal medium for dispersing chemical signals over large areas. In terrestrial environments, chemosignals can be either volatile or non-volatile. When it comes to sex, mammals use chemical signals pheromones to convey information to one another. Mammal's pheromones are air-borne chemical substances released in the urine or feces of animals or secreted from sweat glands that are perceived by the olfactory system and that elicit both behavioral and endocrine responses in conspecifics.
This exclusivity has only been shown in golden hamsters  and the rhesus monkey. Mammalian pheromones can elicit both long-lasting effects that alter the hormone levels of the recipient animal, and short-term effects on its behavior. Odour can influence mammalian mating both directly and indirectly. Odour may act as a direct benefit to females, for example by avoiding contagious diseases by using odour cues to choose a healthy mate. There is vast evidence for the use of pheromones in mating behaviors.
For example, when boars become sexually aroused, they salivate profusely dispersing pheromones into the air. These pheromones attract receptive sows, causing it to adopt a specific mating posture, known as standing, which allows the male boar to mount it and therefore copulate. Regardless of the species, sex pheromones are often structurally similar and for that reason different species need to be able to respond to the correct pheromone. It is the variation in the ratios of each compound within a pheromone that yields species specificity.

February Some years ago, Kate Willis, then one of my students, ran an experiment to determine whether men could tell when a woman was ovulating by smell alone. Six women each wore a T-shirt on three successive nights during each of the four weeks of their menstrual cycles. At the end of each week, 80 men were then asked to sniff the six T-shirts and rate them on a simple scale of pleasant to unpleasant. To avoid contamination, the women had to be non-smokers, and they had to avoid highly spiced foods and using scented soaps or perfumes or hormonal contraceptives while they were involved in the study.
The results were very clear: T-shirts that had been worn around the time of ovulation were rated by the men as being significantly more pleasant than those worn at other stages of the menstrual cycle, and as more pleasant than those worn by post-menopausal women or women who were on hormonal contraceptive pills. It seems that, in some indefinable way, men are more attracted to women when they are ovulating, and can in effect detect when ovulation is occurring. Or, to put it the other way around, women use olfactory signals to entice men into coming closer when they are ovulating.
Such effects work both ways, of course. Androstenol is one of a family of steroids formed as a natural by-product of testosterone, the so-called male hormone. It's responsible for the slightly musky smell that men naturally have, and is one of the components of truffles. In an infamous experiment, three psychologists, Gustavson, Dawson and Bonett, once sprayed androstenol around half the cubicles in men's and women's toilets.
Then the researchers recorded how often users who had a free choice of all the cubicles ie none were occupied entered the ones treated with androstenol. What they found was that men tended to avoid the androstenolised cubicles — having ventured in, they would usually back hastily out and find an androstenol-free one instead. But women apparently found the androstenolised cubicles rather congenial — even if not irresistible — and used them more often than the untreated ones.
In contrast, when the same cubicles were later sprayed with a related by-product of testosterone produced in the liver that serves very different physiological functions from androstenol, neither sex exhibited any preference. In an updated version of this experiment, Tamsin Saxton and her colleagues at Liverpool University applied androstadienone another of the same family of testosterone-derived steroids to the upper lips of women at a speed-dating event.
In speed-dating for those of you who have yet to experience this novel form of mating market for the ultra-busy , the women sit around the room at tables and the men spend five minutes with each one in turn, moving on one place when a bell is rung.
At the end of the evening, everyone lists the names of the people he or she would like to meet again, and the organisers then exchange details for them. In this study, the androstadienone was concealed in clove oil to disguise it. To control for the effects of other odours, a third of the women had androstadienone plus clove oil, another third had just clove oil and the final third had plain water.
That allowed the experimenters to separate out the effect of the clove oil substrate from the androstadienone itself. The results could hardly have been more conclusive. The women who had received the androstadienone not only rated the men they met at the speed-dating event as more attractive than did the women in the other two groups, but they were also significantly more likely to ask to see them again.
Somehow, the androstadienone acts on deeply buried brain mechanisms to create a rosier-than-reality view of the hulking brute before you. In a variation on this, Angeliki Theodoridou, Ian Penton-Voak and colleagues gave subjects either a single dose of the hormone oxytocin through a nasal spray or a placebo control that had all the same ingredients of the spray except for the oxytocin. Then they asked them to rate the trustworthiness and attractiveness of photographs of nearly 80 different faces, half of them male and half female, all posed with a neutral expression.
Those who had had the oxytocin spray rated the faces as more trustworthy and more attractive than those who had had the placebo control. Who said romance was dead? And this perhaps explains why a good sniff of a perfume or aftershave close up can sometimes turn your head. The Observer Sex.
Let me start with the first layer. However, the labia themselves can sometimes use a little extra TLC, especially the inner labia. You may notice a sticky white substance building up in the little folds right where your inner labia meet your clitoris. In the shower, pull your outer labia apart so you can gently wash your inner labia with warm water. Use a fingertip to make sure the buildup is washed away. In between showers, you can refresh yourself by gently cleaning your inner labia with a damp washcloth or biodegradable wipe.
If you take a moment to do this before you and your partner are intimate, it will probably go a long way towards helping you feel more comfortable receiving oral sex. You can keep a few wipes handy in your bathroom or purse, or even use some dampened tissue paper in a pinch.
Just make sure to be extra gentle, since the area in and around your labia can be quite delicate. Other ways to keep your vagina happy and healthy: try to wear cotton underwear, avoid thongs, sleep naked or in loose-fitting cotton, avoid smoking, and try to eat healthy foods as much as possible. I just mean that sex can involve sweating, saliva, semen, vaginal juices, menstrual fluid, anal residue, farting, queefing, and so much more. This socialization gets in early and deep, and it is profoundly harmful to our self-esteem and our sex lives.
It makes us feel ashamed of our bodies, and it can make us feel unworthy of pleasure. As a sex therapist, I teach other women how to feel more confident in the bedroom, and I still find myself hesitating to receive oral sex at times too. I get fired up in the moment, and that anger, outrage, and sadness actually help me come back into my body and be more gentle with it. Try thinking about that the next time you find yourself feeling self-conscious about your partner going down on you.
Remember that you only feel worried about your smell and taste because society has programmed you to feel bad about your body. Washing the vulva with water, between showers, can help get rid of must vag smell. You use a washcloth to gently wipe down the area, removing sweat and other sources of odor. When the vagina sweats those fluids create and hold on to must odors. These odor can lock onto your underwear and stay there creating more of the same problem.
You can get rid of musty vag smell by changing underwear daily, or when underwear is sweaty or soiled. Keep extra pairs of clean underwear on you just in case overheating happens when on the go. One of the best ways to get rid of musty vag smell is to change panties twice a day or every 12 hours.
And choose cotton panties over silk. Wipe from front to back. Wiping front-to-back helps bacteria from your anus to stay where it should. The anus has a lot of bacteria that is normal for the bowel to have but are not normal for the vag.
Sometimes a musty vag smell can happen immediately after sexual intercourse, which is a sign of bacterial vaginosis. The mixing of semen and vaginal fluids can cause a musty vag smell. Some lubricants can also change your pH and the odor that comes with it.
To get rid of musty vag smell that comes with sex use a condom to prevent semen mixing with vaginal fluids. Rinse the vagina and vulva with plain water immediately after sex. Peeing after sex helps flush out bacteria before it can travel to the bladder. Weight Extra thigh fat causes extra sweat and overheating as the thighs can constantly be in contact each other. This leads to bacterial growth and a musty vag smell. Exercise regularly to minimize this can help get rid of must vag smell.
To get rid of musty vag smell avoid meat and a lot of oil in your food. High yeast and high sugar foods can also lead to vaginal odor. Eat plenty of fresh, organic fruits and vegetables. Fruits and vegetables are packed with nutrients that help to fight a lot of health problems. This will help prevent extra oil secretion through sweat glands, flush out toxins from the body, and maintain the pH balance. Probiotics support healthy bacteria throughout the body, including in the vagina. Taking probiotics and eating yogurt can help get rid of musty vag smell and help restore the bacterial balance.
Apple cider vinegar has strong antibacterial and antiseptic properties that can help get rid of musty vag smell. Taking a bath with apple cider vinegar can help clear bacteria that cause musty odors. Tea tree oil has amazing anti-fungal properties is antiseptic. These properties help get rid of musty vag smell but ridding the bacteria that causes the smell.
Add a few drops of tea tree oil to pure organic coconut oil, and after showering rub a little on your inner things near the vulva.
Just make sure to be extra gentle, since the area in and around your labia can be quite delicate.

Think about your current or future daughters or nieces, or other little girls being taught to feel ashamed about their own bodies. Tapping into that sense of collective pain and outrage can really help put things into perspective. Finally, I just want to make a quick note that a lot of women have trouble receiving oral sex due to past experiences of sexual abuse.
Sexual abuse can deeply impact your body confidence and the sense of connection you have to your own body. In general, know that your body is deserving of pleasure, and that you taste just fine as you are — but if you'd like to try to make sure you're as clean as possible, the above tips should help put your mind at ease. Vanessa Marin is a licensed sex therapist based in Los Angeles. You can find her on Twitter , Instagram , and her website.
Have a question for her? If someone masturbates or has had sex several times a day, the quality of semen after the first production is usually watery, though this does not translate to a fertility problem should semen be examined at that particular time,.
The anti-sperm antibodies produced by the immune system, forms an antibody-antigen complexes therefore destroying the sperms and result in production of semen that is poor in cell content but rich in fluids. Also, during ejaculation, semen passes through the urethra and out of the penis.
However, a dysfunction bladder sphincter can cause semen to travel backward into the bladder, resulting in a condition referred to as retrograde ejaculation. Testosterone, the male sex hormone, and sperm are being made in the testes. Sperm is accompanied by fluid while traveling to the reproductive system and is further ejaculated or release during the time of intercourse.
Viva Differences. Beta Rays Vs. This normally results to thicker, cloudier and more viscous seminal quality. Clear sperm semen is usually seen as a pre-ejaculated fluid or pre-cum. White sperm has high sperm count. White sperm usually clot as soon as it is ejaculated and then it becomes a jelly-like substance.
Clear sperm does not clot quickly as soon as it is ejaculated. It spreads like a thin liquid substance. The white sperm ejaculation is common in mature males or individuals who ejaculate less frequently as compared to those who ejaculate masturbate more frequently. Clear sperm ejaculation is common to males who have reached puberty or those who masturbate or ejaculate more frequently.
