And to clarify things, dreams and fantasies are not the same as actually doing something. So if your straight friends talk about gay sex, that doesn't necessarily mean that they'd actually do it.

I have to say, that is NOT my experience,..."big hetro guys" usually prefer women, along with little hetero guys, otherwise they are not really "hetro" by definition. Any group of men together usually sort out quite quickly who is completely straight, who is of an oposite polarity and who have doubts! Inject some tension and fear into the situation and it becomes instantly clear who are what, and who the closet gays are.

I used to have a gay aquaintance who was a really nice guy and VERY honest and trustworthy as well,...I would have trusted my life in his hands. However, much as I liked him and admired his handsome looks, it never once occured to me to think about him in any sexual way. When he eventually found a regular partner I (along with everyone else) was completely delighted, but I never thought about them in bed together in the same way that I have thought about men/women partnerships that I know.
