I know how your husband feels, because I went through the same thing with my husband. I have sz and my meds affected my sex life. I had no libido and sometimes I refused sex, and he was very sad, it affected our marriage. After my meds stabilised me my libido went up a little. But I still struggle to achieve pleasure in sex. It’s worse for men, because they need an erection to have sex. Hope your husband recovers. Sorry I can’t say more…
