[afterburn]

I had thought that antidepressants would increase libido instead (make you happy!) Same for recreational drugs coz you often hear of these being used in sex n drug parties, to increase the sensations.

As for antihistamines and painkillers, that's noticeable sometimes when you have the flu and on these meds, erections also dampened but often people think it's the flu rather than the meds.

Chemo drugs? If you need these, probably won't be thinking of sex already!
