I have been masturbating for a long time. I have started it from an early age like 6ys. Today I am 22. And I still masturbate. But few weeks ago (7-8) I came to know about the sex chat on the internet so I started doing it. During sex chat I always had erection that lasts for 6-7 hrs everyday.The erection remained as long as I chat which goes for 6-7hrs. I masturbated like almost everyday and sometimes for 3 times in a day. But now I am feeling some pain in my veins of the shaft(penis), I also noticed that there is some kind of lump of the veins like a small gap or pit ( I think some kind of veins displacement has done). I am so worried now. I don't feel pain for long. It pains until the erection. And when I try to make more hard I feel pain emerging from that vein lump. Also, when I press that lump of viens i feel pain otherwise there is no problem. I can still masturbate and there is no problem. Also when there is full erection there is no pain. I feel pain when either I press that area of lump or when I try to make my penis even larger.Pls someone can help me. Should I be worried about it? Is it happening becoz of the excessive masturbating ?! Pls someone help me.
