Americans evidently do not have enough healthy, fulfilling sex, and have too much time on their hands. This leads to a preoccupation with sex, and the latest evidence of this is the widespread fascination with slutty Karen Owen's "sex thesis" in which she rated the performance of 13 partners while she was pursuing her undergraduate degree at Duke University. If you have nothing better to do than fascinatedly read about some college athlete's penis size and how good he was or wasn't in the sack, you need to get a life.
Once again, we learn that if you behave badly on the internet, it's probably never going to go away. And that women are capable of even more objectification than men (there is no equivalent to some women's preoccupation with penis size: and I, to be extremely frank, have never heard men have the fixation with very tight genitalia that would be the closest direct equivalent, from a man's perspective- which can be taken care of through a few minutes' worth of exercise by a woman every other day, in any case). The things that some men focus on in women can be taken care of by exercise and surgery. Good luck with similar penis surgery.
So, in summary, if you have a happy, healthy, sex life, carry on. Keep doing what works. And if you're a pathetic individual who needs to vicariously live through others' lurid accounts, you need to change something.
