I do not think that a doctor would be any better than a combination of PC and PubMed. Medicine, and psychiatry especially, is a matter of trial and error. Doctors do not have a crystal ball. The side effects of any given medication are unpredictable. Doctors cannot predict which medication would case SSE (sexual side effects) that OP desires. Only trial and error would show what medication produces SSE in OP. As for the rate of SSE's in clinical trials, those can be obtained via PubMed or general web search.

Usually, people try to avoid SSE's. To desire SSE's is highly unusual, so I can see how someone would pose this question to an anonymous audience on the internet rather than his GP.
