Im bi polar and my medication is ruining my sex life.

Im in a monogamous relationship. My boyfriend supports my mental heath and if he has to he will shove the pills down my throat if i just "dont feel" like taking my pills.

Problem is, along with my mood stabilizer I am taking prozac. Prozac and sex apparently do not mix and im having extreme difficulty reaching orgasm or even being interested in sex. Though ive explained to him what is happening he still believes that i dont want to have sex "with him". So not only do i not what to have sex but im also irritated with his assumption.

How do i learn to deal? Should i give in and have sex....and fake it? Or is there another way to make his understand that its not him its the prozac.
