How to go about this

I switch up some days I act perfectly normal and others I am a full blown little. I love dom amd submissive play but my boyfriend absolutely hates the idea of being a dom/daddy I've talked to him about it and he thinks it's weird but when we are in bed he sometimes likes to dominate me, make me beg to cum, and or beg for his. But I have to force myself out of little space alot because he just doesnt feel comfortable with it. Idk what to do I wish he would give it a try but he wont. What do i do
