Talk to Urologist on Premature Ejaculation

I am 25 year old, single male. I have an issue of premature ejaculation. I have been mastubating since puberty and been facing this issue since the beginning like I get done within a minute. I do workout daily, eat healthy food/fruits, I don't watch porn. I've tried start stop technique but no improvement as such. A friend suggested that I should do it more often to get better at it but no improvement, at times I do it 4-5 times a week and at times once a week or once in two weeks but these days it's just once a week. Kindly give advice. Thanks
