How do you guys feel about PDA?

I feel that PDA is good but in a sense like it's too much. Like kissing in public is good and all but I am kinda of shy and I wouldn't want to kiss like in a movie theater or like outside with ure friends. I feel that if ure on a date and it's outside where the mood is right then yes u should do it. But infront of everyone would make anyone uncomfortable....i just hate it when people kiss right infront of u. it's not a jeasouly thing but it just feels like maybe u should tone it down.
