Is Low Sex Drive Normal While On Oxycotin, Xanax And Cymbalta?

I am a 49 yr old female. That is also post menopausal. That also suffers from sever arthritis in my neck , shoulders and hands. I'm currently taking oxycotin, xanax, and cymbalta. My partner is upset because I am content with having sex twice a week. He wants it every day. Is my sexual behavior normal given my conditions and medication?
