SSRI antidepressants have been shown to delay ejaculation in men treated for different psychiatry disorders. SSRIs are considered the most effective treatment currently available for PE. These include paroxetine, fluoxetine, sertraline and more. The use of these drugs, that require chronic therapy is limited by the neuropsychiatric side effects. New SSRI drugs specifically targeted to treat premature ejaculation (e.g. dapoxetine) can be taken on an as needed basis and have been recently shown positive results in large phase III studies. Nevertheless dapoxetine is not yet approved by any regulatory authority around the world. There is speculation that some of the associated effects are caused by lowered libido and blood pressure as well as lowered anxiety levels. Other pharmaceutical products known to delay male orgasm are; opioids, cocaine, and diphenhydramine.Local anesthetic creams (like lidocaine, prilocaine and combinations) have shown to be very effective in clinical trials and are being used of the treatment of PE. Their use is limited by its own anesthetic effect that reduce sensation on the penis and vagina

The only well studied method is the "squeeze method," where, when the male is close to ejaculation, the either partner uses their hand to squeeze the tip of the penis hard to prevent ejaculation. This was studied by Masters & Johnson, and you can do a search on "squeeze method premature ejaculation" to find the specifics.There are other methods that I'm sure will come up, but I would suggest not investing in any type of supplements unless they have a long track record, are well studied, or not very expensive (or not aggressively marketed).Of note, many of the new antidepressants have no appreciable side effects except for delayed orgasm in at least 60-70% of men who take them. Obviously, this needs to be discussed with your physician, but this would be the easiest medication option.Good luck!
