I am 26 years old man and I am uncircumcised. Recently, I got into cyber sex. During last three weeks or so, I masturbated everyday, nearly 2 hours a day. Several times, I knew I was hurting my penis because I felt kind of hurt and irritated. In addition, I did not use any oil or lubricant to lubricate my penis. I also did not wash my penis after I ejaculated. Anyway, starting from two three days ago, I began to see strange looking dark patches at the tip of my penis, especially, around the opening area. To me, it looks like irritated group of penile papules. It looks slightly inflamed too. When I touch it, it does not hurt. However, my penis feels sort of itch. When my penis is erected, it is less noticeable, but when it is not, I see clear dark patches around the opening of my penis. I also found myself urinate more often than usual.
For your reference, I have not had sex about a year/half. I remember having similar problem on my penis before. I experienced similar problem on my penis after severe masturbation. However, this time, it looks much more apparent. I like to know what this is. I just presume I got an infection. Please let me know your opinion on this problem.
