Ok Guys, let me start by saying that the last time I had a blood test was 1 month ago and the result showed that I don't have any STDs. When I was 15 years old, my prostate produced a good amount of Precum, By just thinking about sex, I see some Precum on my Urethra. But as I became older and now I am 21, my Prostate produces much lesser Precum, to the point even If I think about sex, nothing will come out, but If I masterbate for 15 minutes, only some Precum will come out. I asked my younger brother who is 19, he told me that he produces a good amount of precum and If he think about sex, he will be drowned with Precum. You might say that I don't eat well, well I assure you that I eat fruits and vegs daily, and I don't drink and don't smoke, and I also do jogging/running daily. And I also assure you that I cum alot. As I read on other websites, some men produce alot of Precum and other men don't produce precum at all, so.... what do you think Guys?
