I already did, been so since 3 days a go. Ginger, dandelion root, ginseng, ginko biloba, and a bunch of other supporting nutrients.
I am running an experiment, to help keep my potency to max for all day desire. I am pretty sure when sperm counts are high, that is a time I need to jack off. Ginger does it instantly some how. Ginseng acts by dilating blood vessels for an errection, and has percursor for testosterone. Powdered ginger is in a form that digests fast, and significantly raises sperm count and motility, jessus christ. When you count the fact it takes 2 days at least of some sorts to bring counts to optimal... Hmmm......
