5. Male orgasms last longer than you think
The male orgasm starts with ejaculation. It can last longer than most women think. Men don’t ejaculate because they had had an orgasm, they do so because they are orgasming.

Human eggs can be penetrated by hamster’s sperm.
8. The clit is much bigger than you think
What most people think is the clitoris is actually just the glans of the clitoris. The clitoris is actually a much larger organ that extends internally around the vaginal opening and has a ring around the vagina itself. Odds are that internal orgasm are actually clitoral orgasms. It is mostly comprised of erectile tissue and so can “get hard” with proper stimulation.

As a man ejaculates, you can gently compress the base of the penis which is concealed in the scrotum to reach greater levels of pleasure.

11. The penis and the clitoris are anatomically the same body part

13. Most women can’t orgasm from penetrative sex
Most women can’t orgasm from penetrative sex. Depending on the study, it can be as low as 20% or as high 50% that can. I can’t remember if it was Masters and Johnson or Kinsey for the high number. Most studies I have read that it is around 1/3 of women that can orgasm from penetrative sex.
95% of women can orgasm from clitoral stimulation.
I am not saying that the majority of women don’t want or enjoy penetrative sex, but the for the majority a man can pound away all day in every position and she isn’t going to achieve orgasm.
You would be surprised how many women don’t even know this. They think they or their partners are doing something wrong or they are the minority, the reality is they are the majority.

15. You still produce semen after a vasectomy
After a vasectomy you still produce semen. I thought you would just get the feeling but nothing would come out again. I never knew sperm and semen were not the same thing until the doctor performing mine told me. The only difference is sperm from the testes doesn’t get mixed into the semen after you have a vasectomy. You won’t be able to tell the difference.
16. There’s a reason why some people sneeze when they’re aroused
The nose has the same kind of erectile tissue found in the genitals, which is why some people may sneeze when they get aroused.
