OK, I've been riding crotch rockets for years, and keep having the same occaisional problem. Sometimes when I'm getting on my bike something is going on with my jeans or underwear that gives me a painful pinch in my dick against the tank. I'm not sure if its my dick being folded in some way and then being squeezed tight against the tank, or maybe a crease in my jeans strangling my dick as I sit down, but I do know that it's excruciating. Like I've said I've experienced this from time to time for years, but last week it happened twice, both times wearing Kevlar jeans and briefs. Anybody else experience this, and if so, ever figure out how to avoid it? Any help would be really appreciated.
