Viagra.......

Seriously though, I can't give any advice about the pills. However, it is worth talking to your doctor about your weight, testosterone/estrogen ratio, etc. Even though, some of the testosterone treatments, oddly enough, may lower sex drive. If you're over weight, the odds of lower testosterone is significant.
