Don't really care, I have male and female gay friends and it doesn't bother me.
Because the majority of my friends are straight I do tend to put the sexuality of my gay friends as a fairly major identifying feature in my mind, not in a negative way though (I don't think, anyway). E.g. I know two guys with the same name, one of whom is straight, the other is gay. So in my head when I distinguish between them it's like: [friend], german, in the army, a twin, brown hair; [friend], gay, works @ wherever, blonde, good dancer.
And like in conversations if someone says [person] and we're like which one you pretty much always say ''gay X'' or ''german/army X'' just 'cause it's an easy distinction and neither of them take offence to it.
