I recommend to every guy who asks (you're all the first), to buy some sort of sensitive-skin version*, and try it once, at least. I've NEVER had a problem with hair removal cream except on my chest (don't laugh), but only because I didn't really follow the instructions properly.
They're simple, but important:
1. Get naked.
2. Smother a lot of cream on, but don't rub it in, just make sure everything in the desired area is covered.
3. Wait a good 4-5 minutes (a few minutes less than whatever it says on the product).
4. Stand in a STEAMING HOT SHOWER for 2-3 minutes (i.e., the rest of the time).
5. Test a little area first.
6. It should just basically all peel off to the touch in a giant globby clump.
7. Clean your shower afterwards.
8. Enjoy life.
