Hey, The other day, at soccer practice, I did a diving header and I slid on my stomache when I landed. When I slid, my dick must have hit something on the ground because it hurt a little bit. Then, today, my dick was a little sore. When I took a piss,I looked at it and realized that there was a large, swollen bumb that was a litle read on the top of my dick. It felt like a bruise and was a little more than an inch in diameter. I am not sure if I I bruised my shaft when when I did the header or I just landed in a way that put pressure on the spot that might have been already swollen. The part that hurts id only on the top of my shaft, not all the way through, in the center, or on the underside. Also, it doesn't hurt to piss.
Does anyone know of any possible things that this sounds like it could be in case it isn't just a bruise? cancer? any deseases or common problems? does this sound like it could be potentially dangerous enough that I should bear the embarassment of going to the school's infirmary? (I'm at preseason for my boarding school)
