1 of two things, both i've gone through:
1. excess of vitamin C. Have you drank alot of OJ or had alot of fruits lately? It burns like fucking fire.
2. if it feels like you're going to piss your pants after going for hours afterward, it might be tears in your urethra. Nothing they can do about it, just let it heal naturally. Happens to me every now and again, and it sucks.
