Sex, as a science, has many unknown facts. Recently, British sexologist Sadie Cayman summarized the new discoveries in sexology in 2013 in her new book "369 Facts That Will Make You Sexually Interested". We have selected some of them to share with you. 1. At least 100 million sexual activities occur every day around the world, which means that at this moment when you are reading the newspaper, 65,000 couples around the world are having sex. 2. Researchers at the University of California found that men who help with housework get 50% more sex than men who don't do housework. 3. If a man no longer has sex, then his penis size will also decrease. 4. Semen is rich in protein, which can help the skin prevent wrinkles and anti-aging, but it may also cause skin allergies. 5. One of a man's testicles should droop a little lower than the other, so as to ensure that the two testicles will not collide when the man walks. 6. Greeks have sex the most of all countries, with 87% having sex once a week. 7. Wearing two condoms does not ensure better safety. On the contrary, due to friction, it will increase the chance of condom breakage. 8. Men prefer women with plump breasts, slim waists and round buttocks. This is not because they are lustful, but because such women have strong fertility, which is a necessity for men's evolution. 9.60% of people prefer to have sex with the lights off, as it is easier to orgasm in the dark. 10. The report shows that women can reach orgasm up to 134 times in an hour; while men can only reach orgasm 16 times. |
