emily learns 15 things about penises.

1. smoking can shorten a penis by as much as a centimeter.
2. doctors can now grow skin for burn victims using the foreskins of circumcised infants.
3. an enlarged prostate gland can cause both erectile dysfunction and premature ejaculation.
4. the average male orgasm lasts 6 seconds (women get 23).
5. the oldest known species with a penis is a hard-shelled sea creature called colymbosathon ecplecticos (which is greek for 'amazing swimmer with large penis').
6. circumcised foreskin can be reconstructed with plastic rings, caps, and weights (and potentially years of stretching until coverage is obtained).
7. only 1 man in 400 is flexible enough to give himself oral pleasure. however, it's estimated that all 400 have given it their best shot at some point. (i want to starting polling this one - male emily blog readers, thoughts?)
8. there are two types of penises: a grower (expands and lengthens when becoming erect) and a shower (appears big most of the time, but doesn't get much bigger after achieving an erection).
9. 79% of men have growers, 21% have showers.
10. the average intercourse lasts 2 minutes, 50 seconds (which is probably why many women never achieve an orgasm, and, if they do, it's also probably why they are rewarded with an extra 17 seconds).
11. the longer a penis, the better 'semen displacement' it'll achieve when having intercourse with a women flush with competing sperm (hmmm. so. size does matter. hmmm.)
12. king fatefehi of tonga supposedly deflowered 37,800 women between the years of 1770 and 1784, which is about 7 virgins a day (which, according to my calculations, should have only taken up like 20 minutes of the king's time).
13. better-looking men have stronger sperm.
14. no brain is necessary for ejaculation, that order cums from the spinal cord.
15. the most common cause of penile rupture: vigorous masturbation (for women, it happens after 9 months, 2 minutes, 50 seconds when their vagina explodes during childbirth).
