I think it's just one of those subconscious trigger things. Happens to me sometimes, too. And the fact that it bothers you is proof positive that you're the furthest thing from a bigot.

Yeah, it's just...Gah!...So frustrating...

Meh, you're just feeling a little hetero guilt. What with the way gays and lesbians are pleading and fighting for basic human rights to be delivered by straights, it's hard not to feel some.

You think "he's gay" on a subconscious level, because he is. Where is the shame in that? There is nothing more wrong with that than if you went: "He's that guy who always wears that yellow charlie brown t-shirt" or "He's that guy who won the lottery". It's a specific thing that sets him apart from the next person.

Sometimes when I see a woman on the street, I will imagine what she would look like with a dong in her mouth. Sometimes I'll see an obviously gay guy, and think the same thing. Does that make me mysoginist? Homophobic? Hell no. It means I have an overactive imagination and a healthy interest in sex. ^_^

Thanks, man, putting it like that actually does make it bother me less.
