Most Helpful Girl
Friendly kiss on the cheek- Sure, I don't care, I give my guy friends pecks on the cheek.
Friendly peck on the lips- Eeeeeehhhh... I might be okay with it, it would probably take some getting used to.
Long kiss/make out with another girl- Yeah, no. None of that. I'm not cool with that.
Some people won't have a problem with it, and that's just fine. It all depends on the terms of your relationship. IN the relationship I'm in now I don't want my boyfriend kissing other girls. But in a future relationship the terms might be different.
