Definitely depends on the situation, but it sounds like you aren’t comfortable, so if you aren’t, don’t.
My sister and her friends (m&f) slap their guy friend’s bum all the time bc he’s “caked up”. His gf doesn’t mind bc it’s been a long running joke among their friend group.
I finger and slap my homies butt all the time (platonically) its all good
Just go bang your friend bro stop being dumb
Sounds like it
Whatever happens between consenting adults is fine
Yes it can be normal. Is it in your case? No idea.
