I'd think it's about romantic and sexual attraction, not necessarily about who you have sex with. As a matter of fact (and the topic starter is a perfect example), many cross-dressers aren't really romantically or sexually attracted to men and are not interested in having a relationship with a man (unlike, say, gay men). They're mostly into having sex with men with themselves in the female role and with a female presentation (more or less). This might sound nit-picky, unless you're actually gay. Anyway, I think it's fair to say that the topic starter is not a gay or even a bisexual man, just heterosexual with a kink.
