A couple of years ago a huge guy retired from the NFL (linebacker or such). Wrote a biography in which he said that after the games he would join the other guys and go to the bars and clubs, pick up a woman or two,leave the place with them, then give them their money, say thank you and go home to be with his lover-partner.

Nothing new there in a way, because around 5% of ANY population (from a sport club to and entire country) is gay. Of course if an NFL player said so today, that would pretty much be the end of his career. But the facts are there. Appearances can sometimes be very deceiving.
