My boyfriend likes bdsm

I don’t have a clue about what it is and he won’t really talk to me about it. This may be surprising but he’s cool with his ex and we’re actually good friends. She said that he was versatile too ;v; I guess meaning he likes being the dominant and submissive? I really have no clue about this stuff but I want to give my boyfriend rlly good sex so what should I do? He seems like a dominant around me though 😥 bc he has this cute little jealousy anger thing. He won’t talk to me about it and when I asked “what do you find hot?” he always replies “I don’t know🤔” I mean I just wanna be able to make him and his dick happy bc I bet his stroke game is good af😍😍 yes I’m trying to have sex with him for the first time lmao. We’ve sexted and stuff but like nothing physically 😑

PS. I have a thing for glasses but I wouldn’t say it’s a kink? It’s just a weird attraction I have😗❗️
