Aww damn... Get off me bitch!

I'd hold hands with my girl, or put an arm around her, and I'd consider that to be entirely acceptable. I'd also kiss her discreetly, and lightly, but if it's anything more than that, it would be just plain rude to the other people around us, and neither of us would be comfortable with it.

Even if it were a technically "public" place, and nobody was watching, there would still be a limit to what I'd think of as acceptable, and it would never include "dry humping". That shit is reserved when we're back in our homes, and I don't even understand how anyone could be comfortable going that far in public.

Jam it back in, in the dark.
