When I was first discovering the joy of masturbation, I did it so much that I'd rub the spot just before my head raw. I was really broken up about it, too, so I tried to find some way around it, something I could use to cover up the raw spot. I ended up using Scotch tape, and while it did work for a little while, it was a BITCH to take off afterwards.
I've never put Scotch tape on Mr. Majesty since.
