My Engine Starts And Finishes At The Same Time!! Please Help

I'm physically fit too. I exercise every week and can comfortably run 10 laps of a standard football pitch, so I don't think it's simply a fitness issue.

I've tried pelvic floor exercises, watermelon, and the ginger + garlic + honey remedy shared by Yemmit90 here on Nairaland, but none has helped (I don't know if I did it wrongly).

To be honest, this has affected my confidence so much that I now avoid women. Imagine chasing a girl who's been forming hard to get for over 5 weeks, only to finally get the chance and finish in less than 5 seconds.

It's honestly embarrassing. If anyone has genuinely overcome this—whether through medication, a doctor's treatment, or something that actually works—please share your experience. I really need help.
