I dont care to really see big displays of affection, don't know about the people involved in that.
Far as for me, don't really like the really kissy kissy, mushy type especially out in public. Don't mind if I'm "in love" but still has to be in moderation in public.
Never really thought about if the person who is actually making the big display if it involves confidence, but in analyzing a little maybe it does.
I say this only because I've only had 3 dates w/a guy recently and he's on that mushy crap. Every time I turn around he wants a kiss. Sick of seeing his lips puckered up and poked out. Everything else is nice about him, but no matter how many times I told him to chill he won't. He thinks its showing affection. To soon for all that. Last straw, he started kissing on my neck at a karaoke bar, made my hair stand on end and I'm completely shut down to even wanting to deal w/him anymore. Just been avoiding him lately, now I'm am wondering if it is a confidence thing..... hmmm... interesting. I still don't want him, but never really looked at it like that. Good question
