Favorite sex positions

My boyfriend and I usually do the same 3 (ish) positions. All with him on top. Like missionary etc. I don’t like riding him because it hurts me legs.

I was wondering what your guys’s favorite sex positions are or ones that you recommend. We aren’t new to sex with each other, we just aren’t adventurous when it comes to positions for whatever reason. We also both have only ever been with the other. Thank you!!

PS. We are kinky and into bdsm. He’s the dom and I’m the sub. We also don’t live together.

PSS. I also don’t give him blowjobs. It stresses me out and he knows that and is ok with it. In case this matters for whatever reason.

Ok thank you again!
