Ho do I prevet from ejaculating prematurely?

Research has found that there may be a link between nitric oxide levels and premature ejaculation (check out the article below). There are several ways to increase nitric oxide, including foods (grape juice, green peas) and supplements (horny goat weed, l-arginine, tribulus, tongkat ali, etc.). I take Spartan Blend and do Kegel exercises, but you should ask your doctor before you take anything- especially if you have a heart condition. If you're under 18, don't take anything. If you are looking for more research, you may want to search Pubmed for more studies.
