What supplements help with sexual function?

Sorry but no supplem: "sexual function" is a pretty vague term which can refer to sex drive (libido), ability to get or stay aroused/erect, and ability to orgasm. Unfortunately, there are no over-the-counter medications, herbs, or dietary supplements to improve sexual function per se that have been studied & published in peer reviewed journals. However, improving one's own health can go a long ways towards better sex.
