Hi I'm 17 years old.

The meatus looks slightly red and slightly inflamed (worse after masturbating, which is usually 1-2 times a week). There is a burning sensation when I pee (unless it is very clear urine/strong stream) only at the very tip, which leads me to believe the Meatus itself is inflamed, and it is not some problem in the urethra.

This problem has been persisting for four years, and the first time I went to the doctor I was told it was my foreskin (not retractable) which was irritating it. The frenulum was tight or something like that, and after discussion with doctor/urologist, and a couple of urinal analysis (to check for infections etc), I got a circumsision at age 16. This helped the non retractable foreskin problem (obviously), but did nothing for the meatus.

I've been given unprotected oral sex a couple times, but the issue started before that, so I'm so sure it is an STD or anything. I've seen a doctor a couple times about it and they keep saying it is nothing, simply an irritation. I am a competitive distance runner and train alot in running shorts, so there will be rubbing there.

It's not so much an appearance problem, doctors have said it is only slightly pronounced, the burning just slightly irritates me. If it really is nothing, I could probably live with it but I really want to know what the issue is. Is it a soap I am using (dove), or is it lubrication for masturbation (generally just lotion) ? I recently used shampoo (BAD idea, I know) and it got a fair bit worse. Do I just have a really sensitive glans?

Help me out here!?
