Yes that too, by all means go ahead and give your other half a kiss in public, but keep it respectable I don't get disgusted by seeing people of the same sex doing it, but I think it's more I see it, try to put myself in their shoes, and just get grossed out by the thought of myself kissing a girl But I imagine part of it is having been brought up to see it as being wrong, so there's that background there for it, so I definitely don't see it as wrong, weird to see. I don't know, I'm rambling now
I try not to make a habit out of watching people's public displays of affection anyway, haha xD
