No Sexual Chemistry?

Hi guys, I’m 20 and I’ve been with my boyfriend for 2years and we’re each other’s first everything. Because i’ve never been with anyone else before i find it difficult to know what i like from someone else’s touch but i can make myself orgasm by rubbing on my clit. I try to teach him how to do this but he still doesn’t seem to get it. I don’t cum from sex but he does. His oral doesn’t do anything for me. I hate that everything is perfect except from sex/sexual acts and I really don’t know what to do. I find myself dreading sex cos sometimes it hurts too. It’s also getting frustrating now watching him cum while i’m being left unsatisfied every single time. Does anyone have any tips that helped improve their sex life - is it time to involve sex toys? Before anyone says COMMUNICATE we do all the time but sometimes he struggles to translate this in his physical actions, hence why i’m still struggling to cum. Thanks for the help in advance!
