OMG--you like teeth on your cock? I have only known one other guy who did, and wow, did he get off on it. Sorry, just had to say. I am very much amazed right now.
I believe you--the guy I was with who liked it REALLY liked it. I really didn't mind doing it after I got used to it, but I was always afraid I was going to hurt him. He liked to be scratched too (and to scratch).
I wish I had known when I was in Milwaukee a couple weeks ago. Could have made a sad situation way happier (and your back a lot more scratched up). Yummy. I have awesome fingernails.
