20 Unknown Sexual Facts

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".

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. Next time he falls asleep after ejaculation, don't think he is tired, but that your love finally helped him relieve the pressure!

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.

Having sex during menstruation has benefits. Are you annoyed when you mention sexual intercourse during your period? Don’t be annoyed. When you orgasm, your uterus contracts, increasing the amount of menstrual blood and shortening your period. (Editor’s note: foreign experts’ opinions should be followed appropriately.)

Sexual intercourse usually lasts less than 10 minutes, and we have all seen those montage movies where a couple has sex in different locations all night long without having to eat or even go to the bathroom. But those are all edited long films!

Sexual intercourse does not diminish with age, and senior citizens do not spend all day lining up to buy reduced-price tickets to see a movie. Many of them are always busy and having fun! If your sex life seems a little dull, don't blame it on age. "For a lot of older women, the reason they don't have sex is just a matter of opportunity." Just make some time for sex.

You may not want to tell your man that a man only ejaculates a teaspoon of semen at a time, especially if he thinks he ejaculates a quart of semen every time you have sex. "Except for the odd one, most men ejaculate about half a teaspoon, maybe a little more if they haven't orgasmed in a while," Paget said.

Humans and dolphins are the only mammals that enjoy sex for pleasure, and in fact, as humans we can enjoy sex for the sake of more than just procreation. Don't take sex for granted. Turn up the volume a little at night, play some soft music, light some candles, and be like a dolphin.

Sexual intercourse can relieve stress and prevent disease. Regular sex life will increase the level of immunoglobulin A antibodies in your body, which will help drive away the cold and prevent infection. So, if you really need an excuse to have sex, this is it.

A woman's orgasm is endless, but after a man's orgasm, his penis will become flaccid and enter a recovery period. Women don't need this kind of downtime. The two have multiple orgasms, but the man must master certain techniques to achieve them. That is, a man must understand his body well enough to know when to reduce stimulation before ejaculation. Once he does that, you'll have orgasms all over you!
