I don't really have any sexual orientations, besides heterosexual, in any of my characters; but I'm not saying that I haven't had a character with a different sexual orientation, which I have.
I don't find it disturbing to see girls with girls/boys with boys, or really any other relationship, it's love.
Since I'm not good at role-playing "romantic scenes" with people, I don't normally welcome anything dealing with that sort of thing with great interest, but I wouldn't mind if a character with a the same sex as my character would start flirting or have a crush on my character; of course my character would most likely be blushing the whole conversation.
-Le cough; moves back to topic- It can be pretty dark in the world, and despite sexual orientation, people need love. :3
Love always helps~
