hello, I am a 22 year old male in good health, however a few days ago I noticed a few red pimple like spots on the underside of my foreskin. They do not hurt to touch and have not blistered although they seem to itch a little. I have felt like I need to urinate more frequently. I did have unprotected sex about six months ago which I assume is longer than the incubation period for herpes. Could this just be friction burn or a reaction to a hygiene issue? Or is there something more concerning here?
