A question about Gay/ PDA? For straight and homeual people?

I'm a , my girlfriend uses the old take a picture, it lasts longer. I'll either stare back if that's what they're doing or ignore. Except for once. Some jerk tried to physically tried to break us apart while we were kissing, you know the "violence begets violence" thing? I think it's Shakespear. I just put my leg behind him and pushed. NOBODY touches me or mine unless we want them to.
