Hi, I am 15 years old and is not circumcised. After I arrived at puberty, I've been more horny and felt an urge for sex. Since I have no girlfriend, so it becomes much masturbation. A few days ago, I noticed some spots on my penis, there were some wounds. Since I'm a pretty shy kid so I have not had sex yet, besides the 16-year limit. There was a time doing it hurt when I peed, I tried the latest 20 minutes ago to masturbate it hurts current wounds, but it was strange when I got spermed, it really hurt for some reason and was wondering if in this Might Be somekind of STD (Sexual trans-infected disease)? If it is it's really weird beacause I Have not yet had sat sex.

What type of lube or oil are you using when you masterbate

What type of "wounds"

And are you having some contact with the sex organs of others ?
