should i break up with my partner if our sex life isn't great

im 20F my partner 20NB, weve been together for 4 years now, i feel so happy with them, they are my light and are so sweet...but speaking in terms of sex they feel a lot of dysphoria on their body so they only give me pleasure but dont like to receive it, this will never change and sometimes i wish i could explore more...im riddled with questions and anxiety and i cannot give myself an answer...i feel kinda trapped, we do not have sex frequently and now my want to do it is so low...i love them with all my heart i wouldnt want to break up...please give me advice

TL;DR; : This is a sample summary of the TLDR rule, all things are bold. Is this going the right way?.
