Spice up my sex life 🌶

So me and my boyfriend have been having sex for the past 4 months. He was my first time and before him I never really thought much into what I was into. He has been with other girls before so when I mention to him I want to try new things and I ask him what he’s into he always switches it around and asks what I’m into/what I would like to try.

I thought since he has experience he would be able to say what he enjoys and I can build on that and see if I enjoy it but when he asks me my mind draws a blank! I’ve tried looking at other people’s posts asking similar things about what I can say during sex or things I could try but usually all of the replies are ask him (or her) or you know what your mans into and I do know from what we have done but it gets repetitive and I would like to try new things! I like it rough and him pinning my arms down or choking but other than that I feel like he’s not said what he is into! Any suggestions on things to say to him during sex or how to bring the conversation up again?
