Like I've previously stated in this thread, I've never had Invega injections. However I did receive Risperdal injections 17 years ago and also came down with severe anhedonia, which obviously suppressed my sex drive. If I could muster up the energy and motivation to jerk off, I could reach orgasm but did not ejaculate.
After switching to Abilify pills, I was eventually able to rid myself of the anhedonia as well as revive my sex drive and the ability to cum. In the past decade or so, I've had several girlfriends and a decent sex life with a couple of them. Since covid hit, I have simply stopped being social and haven't sought out companionship in a while.
