Hi there ~
I understand your concern. I also think that the itchiness and sores with discharge on your penis and foreskinn are actually due to an infection, mostly a sexually transmitted infection. I also think that you need to get tested entirely for a screening for sexually transmitted diseases. I also hope you visit with a psychiatrist
to resolve these issues and a doctor who can order the right tests and get the right treatment for the infection. I hope this helps.
Take care and have a lovely day!
