Wellbutrin is an ndri or dnri? that's supposed to have no negative sexual side effects. Of course for me, it killed my libido. Everything functions nearly normally but I just don't get aroused. I say nearly because I did have a weak ejaculation (along with weak urine stream). But I don't know if it is related to the wb. Anyway, I've been told my experience is not the norm. Most people have no issues or actually have increased sex drive.
