I never use shaving cream, not even on my legs, and I shave it all off. You just have to be careful. I just press the razor gently to my skin and shave. Don't add a lot of pressure like you would your legs. I guess because I have shaved for so long its not uncomfortable to me. Well when it starts to grow back, like I haven't shaved in a couple days, which is rare, it starts to itch a little. Nothing you can't handle. The sex is SO much better too. ;)
Have you considered getting a Brazilian wax? I haven't done it yet, but I want to and will soon.
If you have anymore questions feel free to contact me. - Not you perverts writing in either...Mr "I'll do it for you".
Take Care and Good Luck!
