I've known that I liked girls for around seven years now, but now I finally have a girlfriend. My parents don't know, and whenever they talk about gays it's always about how 'despicable' or 'disgusting' they are. I'm a jr. in highschool, and she's a sr. and my sister is a sr. and I can't let my sister know or she'll tell my sisters. But I really like her, and want to express my feelings in public, and I don't want to hide.
Any suggestions or previous experience?
