Is it normal to feel shame after sex?

When my bf and I have sex I feel so weird afterwards. He's really really great to me outside of the bedroom and I really feel comfortable that he loves me. I love him too and the sex is amazing. But he'll do stuff like slap me or choke me during it or dominate me in different ways. Ngl it really turns me on but also I feel so embarrassed/humiliated. And then when it's over I don't know what to do with myself and I lay in his arms and I just feel so shook. Last night he came in me and today I have no appetite. I just don't know if it's normal to react afterwards the way I do. Someone please help lol
