I used to have this symptom 2 years ago. I tested negative for STDs then as well. It's more of an irritation of the skin. Several factors may cause this; clothing, soap that you use, condom that you use ( I hope you do use condoms). The cause is difficult to figure out. Better check with a urologist or dermatologist.
im only 14 years old and i am still a virgin, but i have a dry spot right where my penis starts to leave my body. about a month ago i started to shave and i thought it might be that but who knows. i stoped masturbaiting about a month ago and i began rubbing lotion on it. this morning i itched it a little and then it almost started to blead, you could tell because it was red. if anyone else has this please let me know
Has a doctor seen this? It sounds like a fungal infection, but you need to get this checked.
