From my experience on these forums and on dating websites and stuff, I've found that gay guys (both masculine and feminine types) are looking for a masculine man.
Now, what do I think of this? I see myself as more 'straight-acting' than 'feminine'. But, this is not because of the way I behave, per se, but more of my interests - I'm in love with clothes and dressing up, Madonna and Britney, and the list goes on and on. In terms of my speech or mannerisms, I'd say I'm pretty masculine, but once again, the words I typically use may be considered 'feminine', but spoken in a masculine way. You get my drift?
Now, most guys I've spoken to have this fantasy of being with a really macho man. I'm one of those guys. But, when I think about it, I've come to realize that I wouldn't be able to have a decent conversation with these 'macho' types - I just don't think I'd have much to say. I've had many straight male friends, but for some reason, I don't think I'd have the same conversations with my 'straight-acting boyfriend'. Call me stupid.
