Is it cheating on your boyfriend if you kiss another guy on the cheek. Even if it means nothing to you and is more of a joke than anything?
Terrible advice from everyone. Yes it is cheating. Nobody kisses a guy on the cheek as a joke. It's your way of trying to dismiss your guilt and backpedal out of it. If it didn't mean anything, then why would you do it?
The fact that you lied about why you did it tells me your boyfriend should not trust you. It might not be severe cheating, but you show signs that you don't respect your boyfriend or his feelings.
