i had sex with my girl friend a week and a half ago no condom twice in a span of about a hour few days later i notice i had small red dots on my penis head .I read up on it started cleaning my penis even better with soap instead of just water since im uncut and they say it happens more often with uncut males so it seem like it was clearing up the bump u couldnt see as well and it wasnt red but the middle of the head was more brighter than the rest of the penis. Well last night i ended up masturbating and after i was done notice that my penis was more red with the red dots visible.so i get up 2day and us the restroom pull my foreskin back and notice the red dots was visible and i had a couple on my foreskin when i pulled it all the way back could this be from friction irritating my skin

if need pic i will post
