it hurts quite a bit. That wasn't the bad part though. The bad part was they didn't completely heal for about 5 years. I finally took them out when they got infected after 14 years in place. They really didn't add a whole lot to pleasure, they got in the way a lot and pretty much everyone is getting them now. I wouldn't bother anymore.
ALOT! They'll spray it with a cold spray so it's stiff, clamp it, put a needle through it. The initial pain's tolerable, the after sting's bad. I had to take mine out after a couple of months, wasn't healing well
