I'm Bi-Sexual. Alot of my friends are lesbians, gays or bi. We're pretty private about our involvement in romantic relationships so we don't really make a big scene for example... kissing or making out in public. Making out in public, no matter what orientation you are, seems rather rude to me.
I mean, I don't care what they do behind closed doors, but I really don't care to see people look like that could just rip each others clothes off and go at it in public. :/
Love shouldn't be forbidden or not allowed for someone to charish if they are not of the same orientation as you. We're human and desurve every right to everything else just like any other person.
