My girlfriend and I have a great and non-problematic sex life. But I'm looking to enhance the sexual drive and pleasure. I was going through a large list of natural aphrodisiacs and here is what I ended up with:
1] American Ginseng root
2] Bee pollen extract
3] Blue Lotus of the Nile
4] Calamus root
5] Damiana
6] Horny goat weed (hahaha! for the name)
7] Tribulus fruit

There are many many more. Has anyone had an experience with these? Do these work? If yes, which one is the most powerful and enjoyable?

Ginseng helped somewhat, but made my eye twitch, so I got off of it. Horny goat weed stopped my menstrual cycles, so I quit taking it. It might be okay for a guy to take, though. Damiana and Tribulus did absolutely nothing for me. I've never tried the other stuff you listed. I'll keep them in mind, though, for my own personal reference. My sex drive has been dead for over a year due to a medication that I was on.

Oh, but did Horny goat weed and ginseng significantly increase drive and sensation?

No, not really. Everybody's different, though, just because it didn't work for me doesn't mean it won't work for you. I've heard great things about both, they just didn't do anything for me.
