Well eversince my sex-ed classes i have been extremely paranoid about STI's/STD's
Anyway well awhile ago i found a somewhat meduim/small sized red spot on the side of my penis, mind oyu i am only 15 never had sex, no one has ever touched my penis and i just masturbate.
The spot appeared after i had masterbated quite alot and it somewhat burned so after time a scab or a red dot appeared im quite confused now.
I have searched about syphilis and my mom obviously doesn't have it, and i have never masturbated with someone else, nor had sex or oral sex.
what can it be?
Please answer i am constantly worrying cause i am a very paranoid person and i can't think straight in school. I get scared easily when it comes to this suff.
Oh and by the way i will soon begetting a blood test for my contact sports, will it detect and kind of STI?
Sorry i am a noob at this stuff.
