Avery,
I haVe known many men in my life who enjoyed anal play and even bottoming. Sometimes they'd let me suck them till they got nice and hard, then they wanted me to play with their ass, and once in the zone, did not want to be touched in any other way. In fact, I've known too many like that. It has often been a disappointment to me and sometimes i'd have to cut them off and tell them I was no longer interested, after all, I was the gay one, and I wanted to be the bottom!
juanjo is so correct. There is no LIMIT, to what some straight guys will do, if approached correctly. And then throw money into the mix! What's more, I'd bet that more straight men will push their sexual comfort zones far more than gay men would. And if a gay guy ,for whatever reason, even dared to hAve sex with a woman (even for $$), would that be enough to label him straight? I think not!
When it's all done and said, I think sexual preferences are very much like food preferences in the scope of diversity and variety of what different people may like/dislike, willing to try, not willing to try.
Some people are strictly vegeterians, and wouldn't touch a piece of meat if their life depended on it. Other vegeterians, could be convinced to try a, for the sake of argument, tube steak (LOL!), if the money was right.
Just because the vegeterian who is paid to eat the tube steak follows through and actually eats it doesn't mean he is suddenly a meat eater. Once he gets paid and goes home, he will most likely become strictly vegeterian again.
It's similar with ANY food! Some people may love cheese, but they hate blue cheese. So this doesn't mean they are strictly against cheese, just certain types of cheese. And they may like desserts too, so that doesn't mean all they eat in life is cheese.
I look at bi sexual folks as very diverse people in their diverse, and all ecompassing love of sex with not just guys, but not just girls either.
Guys who are truly straight and don't enjoy sex with guys, but do it for the money only, are like vegeterians who will eat a tube steak for money.
Personally, I love me some nice meat and potatoes...but I also love my veggies. While I don't consider myself bi, I could definitely be with a woman and love every minute of it because I'm not all the way to the gay side of the scale. BUT, I like my women feminine and my men masculine. I could never be turned on by a butch acting woman, nor a gay acting man.
But that doesn't make my tastes and likes/dislikes weird, EVERYONE has their own preferences with sex, and food.
