hello! i have small red, painless and itchless rashes on the tip of my penis. Without doing much research on it, I have a hunch it may be penile psoriasis? I have not been sexually active with a partner for almost a year now. There has been stress, and I believe I have been masturbating more frequently ( 3 - 4 times a 7 day week). There no literally no symptoms other than looking like a red rash, with well defined borders around them. Thanks so much!
