There seams to be an area in the middle of my penis that is hardened and causing it hard for me to urinate? I can stick a small paint brush end inside and pass in through the area about an 1" and 1/2 down from the top of my penis and then I can pee just fine. It not hurting but I can feel something going on there? I masturbated to see if it was obstructing and yes same results. It appeared last week. It could be an infection? Never had any problems before and I don't usually stick anything down my penis either. Very strange, I drink maybe two beers everyday for dinner and I was taking alot of b-12 with a 500 vit. C. Your thoughts...?
