Gay guys who watch straight porn

[meridannight]

because in theory sexuality is fluid, that's what I have read

Watching porn is not sexuality. Although, it is indicative, even strongly indicative, there are exceptions. I know of straight guys who get off on gay porn, and I have read a perspective on it written by an accomplished psychotherapist, explaining the phenomenon. And, to put it shortly, it does not mean a guy is gay (or bisexual), just because he watches gay porn.

Who you desire to have sex with and to form a physical and romantic attachment to is indicative of sexuality (as opposed to who you experiment with out of fun, newness, availability, etc).

Even sexual behavior is not always a true indication of a man's sexuality (this is where Kinsey got it wrong). Men experiment. A number of straight guys have experimented with men, and they are still heterosexual, regardless of the fact that they had sex and orgasmed with another man. It is my opinion that a heterosexual man can have sex with another man and still remain heterosexual.

The same goes for gay guys. Although I don't include myself under it, gay guys are capable of having sex with women and they have done so throughout ages. It happens less in our age in the Western society, because the social/economic/etc pressure to do so is more or less absent.

The whole ''sexuality is fluid'' theory is misguided and asserted by people who are not able to differentiate between sexual behavior and sexual orientation in man. And it is propagated more out of underlying subjective identity issues (and issues with sexual inhibition), than out of actual sense of one's sexual orientation and/or being in touch with oneself.

People need to learn to distinguish more clearly between constrained behavior, physical act, and actual sexual desire.
