8. There is a best day for sex
Day 14 of a woman's cycle, to be exact. On this magical day (which is also around the time ovulation occurs, go figure), a woman's clitoris grows like a magic grow capsule, increasing in size by up to 20%. That makes it way, way easier to get her off, for those of you who are clueless or cursed with crappy dexterity.
9. Orgasms are the best headache cure, hands down
Orgasms work faster than painkillers to reduce headaches and cured 60% of migraine sufferers in a recent study.
10. ... and the best treatment for period cramps
The contracting that happens in a woman's uterus when she orgasms uses up lipid compounds called prostaglandins, which also cause menstrual cramps. That squeezing also helps to flush out excess blood (sorry guys) and other period-related debris that could potentially lead to endometriosis. Tell that to her next time she says she can't possibly, because it's her time of the month.
11. Lesbians have the upper hand
While straight women only have orgasms 62% of the time they have sex, lesbians get off 75% of the time. That's according to a study published in the Journal of Sexual Medicine and I guess shouldn't be completely surprising since these girls are working with familiar equipment.
12. Orgasms affect a woman's... breath?
Allegedly. Marriage manual author Theodoor van de Velde wrote some patsy book called Ideal Marriage in the '30s in which he claimed women's breath has "a slight seminal odor" about an hour after intercourse. OK, whatever.
13. You can tell a lot by a woman's stride
A bunch of Belgian scientists got together and determined they could infer a woman's sexual history by the way she walked. Real life. Basically they analyzed women's gaits and found that stride length and pelvic and vertebral rotation suggested a woman who was regularly enjoying orgasms.
14. Orgasms are no miracle diet
An orgasm burns just two to three calories, though a person can burn around 50 calories in the activity leading up to the orgasm. Not exactly an excuse to cancel that gym membership.
15. Orgasmic pulsations are some next-level shit
The little round ligaments that connect to the labia move a woman's uterus to and fro during her orgasm, allowing the cervix to pull in semen that might have pooled in her vagina. It's like those baby-making parts have minds of their own, grabbing around in the dark to continue the genetic line. Science!
16. Orgasms make women like you more
When a woman gets off, her body releases four times the normal amount of oxytocin. Which, if you didn't already know, is the "bonding hormone." If she's not feeling cuddly after sex, it might mean she faked her orgasm. Just saying.
