I am 38 yr old male and I take invega sustenna shots every month for psychosis and it's 78mg and since then there is almost no pleasure from orgasms while masturbation. I am concerned this is not good because orgasms are an important thing in your body most doctors would say. I don't wanna be embarassed front of my future partner.I read Peter R. Breggin M.D. He believes and has proved that all psych meds are harmful. Google him and see what he has to say. I have thought of completely stopping invega for good. I don't really wanna try any more medications. Has anyone ever experienced this I would like to hear your opinions and stories... and solutions. Thanks!
