Jabari -
Not being a regular poster, I feel uncomfortable with suddenly acting like a know-it-all. But that said:
Look at PE in the same way you do bodybuilding. High protein, low fat is good. Carbs should probably range from low to moderate - depending on what you want to accomplish with bodybuilding. The best diet for PE and sexual health in general is identical to a healthy diet used during the cutting phase. Lots of protein with all carbs coming from high-fiber sources like fruits and vegitables. And water! Lots and lots of water!
Supplements are a different issue. There is probably no (additional) harm in taking creatine, andro, ECA’s, and other strictly bodybuilding supplements. But for PE, your supplement regime should be based on stuff that enhances the bloodflow rather than altering the blood itself. For the most part, that is. Just look at the ingredients for most of the “Vig-R-Plexitude-argin-plex” stuff that will - of course - instantly make your cock stick out the bottom of your pants. There are basic, “root” supplements that are universal: Ginseng, Ginko, Arginine, Yohimbe, Horny Goat Weed, Tribulus, Saw Palmetto, (blah, blah, blah). Just pick and choose until you find what works best for you or you can most afford. If there really was one right answer, it would have been bottled already and would be the best selling supplement of all time.
Christ, my posts can be long!
