HELP!

I think masturbating to porn for too long has affected my skin, it's rough now, I get itchy all over some parts are dry I haven't masturbated or watched porn in 9 days and before then I did 3 weeks but I've noticed this past few days I've been getting really itchy, I'm tired of not being able to take of my shirt in front of my friends when it's hot cause of the uncomfortable look I get or the funny questions they ask to know what's all over my body this has been going on for a few years now but this few this I'm really noticing this itchiness I just wish I never got myself into this... I get scared sometimes thinking I might be stuck like this.

 

I have never edged before in my life.
