Trouble in paradise

Hello!

Looking for advice or HELP! Lol

My boyfriend and I have been together for just over two years now. We’re struggling in the bedroom lately, we use to have hot sex that we’d both want every day if not more than once a day! He recently started expressing his feelings/concerns. But blaming it all on me, saying that I don’t do anything during missionary feels hes “*aping” me. And I suck at being on top.

I guess I’m not sure what I’m looking for, maybe some tips and advice how I can improve.
