Hi There! I'm not a guy, so I can't give you an answer with a guy's perspective personally. But my husband, while on Opiates several years ago was having problems substaining an erection while on those meds. The problems went away as soon as he stopped taking them. As a female's perspective, I also was on large doses of Opiates and was having trouble reaching orgasm as well as having a low libido while on my meds. They too went away after discontinuing my meds. So hopefully you won't have to be on your meds for too long!! Good Luck! Stace
