Are there over-the-counter drugs available for sexual dysfunction?

Sorry but no. "sexual dysfunction" is a pretty vague term which can refer to lack or loss of sex drive (libido), inability to get or stay aroused/erect, inability to orgasm (anorgasmia), and even (undesired) pain w/sexual activity. Unfortunately, there are no over-the-counter medications, herbs, or dietary supplements to diagnose, treat, cure or prevent sexual dysfunction. Instead, go see your family physician.
