whoa, doing that right there destroyed my cock! Ok, maybe 'destroyed' is a little to strong of a word for it, but before the ring in the middle of it, my dick was straight, always easy to cum and piss... after the one time it developed a sharp upward curve when hard. I have a very hard time cumming and a hard time pissing. all from just one time putting on a tight fitting metal ring in the middle, the fucked part was when I started to realize it was getting to tight my cock started getting harder and harder, which made it even tighter. It just wouldn't go down, took like 30 minutes before I could get it off me. By then the damage was done. The very next day when I got hard it was already noticeable and within a week it had about a 30 degree upward bend. Oh well, Live & learn I guess.
I still love to wear cock rings, just not on the shaft.
