i am 16 years old and about 4 weeks ago i saw a red bump on the head of my penis it was swolen for about a day but then went down. The redness has still not gone away though. sometimes it is very red and sometimes its faded to pink. when i get hard it gets extreemly red im not sure what it is. The doctor said it was probably nothing but its still there and seems to get a little bit worse every day. my head does not hurt in any way its just there and it bothers me a bunch. does anyone have a clue what this is. Please help me and send me any information that will help me! thankyou
