I am so happy I found this forum and I want to share my case.
I am 26 and have masturbated for more than 10 years on a regular basis (2 times a week). Although I can get aroused immediately, I orgasm very fast, too - usually less than 2 min. This became a serious problem when I started to have sex. I always think it is just PE. But I also read somewhere that if one does not ejaculate quick every time, then it is not PE. I usually last longer the second time after a couple of hours, which I think many people do the same.
I do have pois, which I think is related to PE, but not as serious as many other friends in the forum. I can feel the subtle pain in my left kidney area immediately after ejaculation, which lasts for maybe 5 min and disappears. If I orgasm the night before I will have minor brain fog and become less able to concentrate the second day, which are not too bad. The real problem is sore and dry eyes and dark circles. But it usually disappears the third day. Sometimes if I masturbate more than I usually do, like once or twice every day for a couple of days continuously, I tend to feel subtle sting in my waist. But the pain also does not last long and disappears gradually.
I started running on a daily basis 6 months ago. I feel good to keep running but it does not help with my PE or pois. I eat two eggs every day, which is not very helpful either. I also have bad alcohol resistance and I started hair loss since 22 - not sure if they are related to pois.
I think now I will try taurine for some time and see what happens.
