rash/red spots on glans(glands) of penis

Hello. I am a 20 year old male with a circumcised penis and no sexual activity. I have had a condition on the glans (glands) of my penis for almost an entire year now. There is a spotty rash that appears again and again. First the rash will appear and then a couple of days later it will flake and peel off. Then new rashes will appear and the cycle starts all over again. It does seem to be more concentrated on the left side of my glans (glands), more so on the rim and the area surrounding. There is a stinging pain when my underwear rubs on it when walking (I position myself on the right side of my boxers), touching, or masturbating. I also have a strange method of masturbation where I flip the penis upward and rub myself on my mattress so that the bottom of it is rubbing on the mattress and the top of it is rubbing on my lower stomach area (I have hair in this area). I do not wash myself afterward as I tend to just fall asleep right away. I have been doing this for years and years and haven't had this problem up until this past year. Is it Balanitis? Is it a friction type irritation? Is it a sensitivity to a detergent that I wash my undies with? Is it caused by the semen sitting on my penis all night? Ugh I want this stupid thing to go away, it can be so painful sometimes. And I am also getting married this summer so I want to be ready for healthy, pain-free sex! :)

can anyone help me out?

I could really use any advice! I'm kind of worried it's something I should be concerned about

I had something similar - it turned out to be balanitis. I now make sure that I don't use soap - I use a liquid made of natural oils for showering, and use a detergent that is for sensitive skin for washing my underwear.  I also make sure I use talc after showering every day and I have been free of it for about 3 years.
Good luck.
