No offense, of course. I am simply not attracted to girls, and guys really get me going. This of course means I am gay. Duh. I figured that out some time ago. But why do I feel nothing towards girls? It does not make sense.
I'm not sure what you're asking, unless you're asking why you're gay, in which case I'd say it's wired in you to be gay and you can't help it.
I don't feel anything towards guys except maybe friendship and am yeah I'm lesbian . I think the simplest answer is always the best one
