Our sex life is rubbish

So me and my bf have been together for two years don't get me wrong I love him, I'd happily spend forever with him just our sex life's are rubbish.

He's the only person I've ever been with and vis verse we have Sex about once a week and it seems forced for both party's I tried talking to him but he says it feels fine for him so maybe it's just me.

We've tried all the positions ect...

It just never flows we life with my parents so it's hard but when we do have free house he just don't seem intrested

It's quite important for me that because he's the only person I've been with I don't want it to come boring

He's not the type of person I can talk to he doesn't take it well 🙄

Any advise would be good

Our relationship is either real good or real bad so I'm not sure if this is a healthy way of being
