My boyfriend isn't dominant with ME. Advice?

So before we got together he was into some bdsm - he already had a few toys and some experiences with other women, and told me he was into it. It was a huge turn on for me tbh.

Anyway, we've been together for a year and a half now and still haven't really had any bdsm sex. Just regular sex. Which is great... But I'd like to get tied up and dominated. I've talked to him and told him I want this from the beginning, but he says he doesn't feel like he needs to be dominant with me. He just can't get in that dominant mood with me? He also said that I'm just so cute and I guess that makes him not interested in being dominant?

He wasn't ever long term with the other women, so maybe that's part of it. Idk. I just don't understand what it is about me that made him not into bdsm so much. I feel like I'm missing out on some amazing sex and getting to see his dominant side.
