Post in this thread if youve got dating problems you need help with, hopefully someone can give advice. I'll go first

>Been seeing this cute guy I met on Growlr.
>Asian, handsome, smart, cultured, loves to travel.
>had a spa date today (third date)
>he takes off shirt
>I notice bite marks on his shoulder
>"Where did you get that?"
>He says some along the lines of his "pup mentor" or something from last night

Later he explained that it's not a sexual thing, that his "friend" just bites him as a way to "say goodbye", and that's the extent of their friendship.

I'm not really into kinks or anything like that, so should I be worried? I don't do poly or open stuff so I'm in the dark as to whether that type of shit is normal. He says he's a sub, so I'm guessing he has a dominance thing. But other than that, I don't know what all that "pup" stuff is all about.

Thoughts/advice?
