I'm amazed at the diverse set of experiences on this thread! There's viagara (for men at least) but being erect isn't the real problem for most guys. Maybe the drug companies could work on an orgasmic drug that counteracts the effects of psych meds. Chances are, it would be a big seller across the board, though.

There's money to be made there!!! Or, for the bipolar set, they could work on a drug that induces the hypersexuality of mania without the often catastrophic results.
