1) Genetics can affect when a person will lose his virginity

The best time for the first time is an individual decision. However, recent studies show that genetics may influence how early you make that decision. A survey conducted by the University of California accompanied some twins, separated at birth, throughout their lives and found that there is a strong genetic link involving the decision to lose her virginity.

"There is a gene that sends having sex at certain times, but some genetic traits such as impulsivity, affect the decision. Although, of course, social customs also play an important role, "says an author of the study, Nancy Segal.

2) The clitoris is the organ most internal than external

Contrary to popular belief, the famous female sexual organ is like an iceberg: although a visible part, most of the clitoris is located within the pelvis. When a woman is aroused, the clitoris involves the entire vagina, making sex more enjoyable.

This discovery is relatively recent in the medical community. Only in the 90s, the researchers could see a full body MRI system, and in 2009, the world was first introduced to a full 3D ultrasound image of the organ.

3) Semen is nutritious

A middle aged man ejaculates the equivalent of a teaspoon. Each "part" that contains about 15 calories, similar to egg protein, vitamin C, calcium, magnesium, potassium, vitamin B12 and zinc.

4) Sex can help you be healthy

A survey conducted by the University of Pennsylvania found that having sex twice a week can strengthen the immune system, since it increases the levels of immunoglobulin A, whose function is to protect the body from destructive cells seeking to enter the nose and mouth.

Another study published in Biological Psychology showed that frequent sexual activity decreases the levels of cortisol in the body and therefore makes a person less stressed and better emotional balance.

5) Sex makes women more attractive

When women have sex often, their estrogen levels increase and consequently the hair looks brighter and smoother skin. Furthermore, the increase of blood flow causes an orgasm are more pink cheeks and lips redder.

6) There is no way to escape the STDs

The American Association for Sexual Health has warned that more than 80% of sexually active adults will contract some type of STD (Sexually Trasmissível disease) at some point in life.

Although the numbers seem daunting, most people will not suffer any ill effects and will not even notice who contracted sexually transmitted disease. That's because more than 25 types of STDs are asymptomatic. In any event, prevention is always necessary.

7) Contraceptives affect the relationship

A Scottish study examined the sexual and emotional relationship of over a thousand women worldwide. The conclusions were that most of them are sexually incompatible with partners. To maintain good relationships, women are abdicating their wishes in relation to sex.

The researchers believe that this is because the pill affects the brain chemistry of the woman, leaving her more interested in a long term relationship than to find the best partners.

8) Food can alter the taste of semen

Scientists warn, boys, if they want to please their sexual partners, caring for the food! This is because studies have shown that fruits, especially watermelon, kiwi and pineapple, leaving the lighter taste of semen, while beer and coffee cause a stronger flavor and bitter.

Since meat and fish leave the semen with buttery taste, while more acidic fruit and liqueurs can leave it with taste sweeter. Milk, in turn, contains high levels of bacteria and, therefore, can leave the semen with bad taste.
