Found my boos kink...

My boyfriend is a very meek & timid person in the bedroom. He's respectful and loving and just so kind inside&your of the bedroom too! He's mostly just nervous because I'm the only girl he's ever been with and he's 20. He's very self conscious about it but today we tried some hardcore stuff & holy moly. 
He grabbed me throat, called me a bitch and all that fun stuff 😄 & coming from a man who has NEVER ever raised his voice at me the 8 months we've been together.... It was amazing.
Anybody else have this kink??
