Bdsm lifestyle?

Well I knew my man liked rough sex but lately he brings up kinky stuff, more kinky than usual and has revealed more of his past sexual escapades. I'm pretty new to sex, he's my first. I never told him he was my first I just said I wasn't experienced. I think he is trying to get me into bdsm without calling it that and wanting me to be his "slave" or his "little slut". He is very dominant and I'm very submissive. He has verbalized he wants to tie me up, slap my face, and basically hurt me. I'm okay with bondage and light spanking but he's revealing the sadist side of him. I don't really care for pain (anti-masochist) and hes pressuring me a lot. Saying things like "I will do as I please, and you'll just have to take it, ok? you're my little slut" "what if I made you cry" "I'm going to fuck you in the ass next time." I think hes sort of trying to role play but at the same time disrespecting me and not asking if I'm cool with it. Bc I know the number one rule of bdsm is consent. I told him I'll think abt it but he said all that stuff after I said I'm thinking about it which is ignoring what I said.
