You have to stop jerking it to porn let your testosterone levels and mental fantasy reboot itself give it a month or two really you’ll become Saiyan just sayin
Also same reaction from doctors
Currently im trying to find a urologist that is willing to do a surgery to remove the cowper glands.( these produce that clear fluid)
Im 27 now
Had this problem my whole life. Long foreplay is a nail in the coffin for my erection because it leaks the whole time I'm turned on. In masturbation the process is much faster so there isnt a lot of leakage and I'm able to finish. With a woman, I to very short foreplay, penetrate and finish within a few minutes, then fo back to whatever side activities we can think of. Then repeat. Naps work great for new sessions. Time helps of course. Always be relaxed and stay out of your head. Minimize porn. Take erection pills as needed. Hope this helps. It also comes down to having the right partner.
Anyway, encouraging to see I'm not the only one.
