How To Explain My Kinks To My BF

soo, im with this guy for 6 months now, and we have a really great sex life. recently, i have told him that i liked being choked, spanks, getting hit(like slaps on face) etc.. aand he reacted pretty well actually. he is really becoming better at it now, but he says he feels bad afterwards. but i can see him really enjoying what he is doing when we are having sex.

and, i also like bondage, and 'being forced'. but im kinda unsure of how he'd react if i tell him that too? i told him that he doesn't have to do it if he feels rreeally bad but he said it was okay, and he has done these in his past relationships. he said he had never done this with his 'serious' partners. i mean, i am not ashamed of what i love. but i also dont want to push him, or scare him off?

idk. what should i do? any tips?
