Help with ED

I am having a bit of a problem in the bedroom if you catch my drift (ED)... and I'm looking for herbs that will help, so far I have come across a few, the most common are:
-Ginseng
-Horny Goat Weed
-Ginkgo Biloba
-Cnidium
-Ashwagandha
-tribulus terrestris
-Mununa Pruriens

I am considering trying it with all 7 herbs in it, but that will lessen the effect of each chemical from each herb, i am curious on what to do, if anyone has had personal experience in this please help me, if you wish to remain anonymous feel free to just email me w/o commenting here, it took allot of nerve for me too post this here...lol

I have already tried making pills out of the following with mixed results:
-Ginseng
-Horny Goat Weed
-Ginkgo Biloba
-Damiana

Thank you for the advice/help in advance.
