Agreed. The main problem with those penis pills is that, though they contain several different herbs to sound fancy, they don't have any of them in a high enough dosage to actually do anything. So you're way better off just picking one, maybe two, herbs for that purpose and taking just those. And it'll be way cheaper that way.
Try yohimbe. That's a good one that I actually have experience with. I've also heard good things about horny goat weed and maca, but I've never messed with those so I can't really tell you anything about them.
Or just go get a prescription for Viagra. I'm told that works pretty well.
