Enough to show affection -- a touch, a hand hold, a hug, a simple kiss -- but not enough to excite. Foreplay is out!
How much public display of affection is acceptable?
I think it's cute when you see couples who are obviously in love, walking hand in hand, or arm in arm, maybe a small kiss....anything further, I don't wanna see!
Whatever isn't illegal is fine by me.
My husband has never been into PDA' s. When I was younger and wanted everyone to know I had a boyfriend I wished he was more "PDA-y" but I have grown up since then. Lolololol!
Depends upon whether or not you need binoculars to see what they are doing.
I am with everyone else. A hug or kiss, holding hands or arm in arm is all fine. Making out and groping, get a room.
