Boyfriend is always horny

My boyfriend has a very high sex drive. he wants to have sex almost everyday. I am NOT a sexually active person and I have explained this to him. sometimes he comes home from work and immediately he wants to have sex and then if I tell him no his feelings get hurt. I don't know what to do or how to explain to him anymore than I already have that I'm not a sexually active as he is. I suffer from bipolar disorder and depression my medication makes my sex drive low. he says he understands this yet sometimes he still gets me I feel like a piece of meat sometimes

please help

We've been together for 2 years btw.
