11 unknown sex stories

Now let's take a look at the top 20 sex facts that you didn't learn from sex education, you will definitely be surprised!

Sexual intercourse makes you sexier. When a woman has sex, her estrogen levels double, making her hair shinier and her skin softer. "Estrogen seems to be the fountain of youth for women," Britton said. "Estrogen even helps the vagina retain moisture. Think of intercourse as the ultimate beauty treatment and have sex often."

Many women experience bleeding after sex, which can sometimes be caused by an infection. Although most cases are not life-threatening, you should still visit your local doctor to check out what the problem is. If you need treatment they will tell you.

Women also ejaculate, and although this is a hot-button issue, many women claim that they expel a fluid from their bodies before or during orgasm that is neither urine nor vaginal lubrication. This liquid is discharged from the urethra (or the tubes around it). It is colorless and odorless, and can be as little as a few drops or as much as a "pouring".

The orgasm of most women does not depend solely on the depth of penis insertion. Don't expect a man to reach orgasm without ejaculation. Women feel that they cannot reach orgasm without clitoral stimulation.

"Our clitorises need stimulation," Levine says. "After all, the sole purpose of the clitoris is to provide pleasure during intercourse. You can stimulate your clitoris with toys or fingers during intercourse - or have your partner do the same."

Sexual desire is often linked to your menstrual cycle, and it's no coincidence that many women experience an increase in sexual desire during ovulation. When testosterone is at its highest, you feel most frisky—just ask anyone. The fact that we are likely to want intercourse while pregnant is just a little trick of biology!

Falling into a deep sleep right after is the same for both men and women. There is a reason why you and your partner feel tired after sex. Oxytocin is released after sex, and the hormone can calm you down and even put you to sleep.

This time when he falls asleep after ejaculation, don't think that he is tired, but that your love finally helps him release the pressure!

The most pleasurable position for women is on the left side, and according to sex workshop instructors Steve and Vera Bodansky, the clitoris actually has a special area that is most sensitive. "So tonight you guide him like this, "A little to the left, honey!"

It's perfectly normal for women to have submissive fantasies, and if you fantasize about your boss throwing you down on the conference table, you're not alone.

"Studies show that more than 50 percent of women have had similar fantasies," Britton said. Even the most dominant woman may have moments of submissiveness during sexual intercourse.
