I am 30/Male...For the past year, I have been having annoying problems with my penis, when ever I have sex with my pathner, during sex, I can actually feel myself in a little pain and after sex, I notice I have all these cuts and bruises on the tip of my penis. I am very worried about this. I have visited a doctor before, but it seems like he does not know what he is doing. after a day or so, the tip of the penis is swolen and makes it hard for me to urinate because it burns and if I shower, I cannot pull the skin back. After 2 or 3days, it is healed and then when I have sex again, the same thing happens. do you think I need to get circumcised? what causes this problem? I had sex 2days ago and the tip of my penis is still swolen and it hurts badly. what can I do?
