I'm not entirely sure how long i have been unable to direct the flow of my pee but i am presuming it was around 6 months ago when my meatus became red and swollen (looks like red lips/ slit in tip of penis). I feel no pain when urinating nor do i feel any irritation either, and it cant be STD related as i haven't had sex. Before i finally see a doctor about this does anyone know what it is that is causing this? it is preventing me from doing a lot of things as i dont feel comfortable using any public toilets.
