Well, I shave about every week. Anything more frequent is likely to cause stuble rash. I've heard of people shaving every 4 days, but I think that's pushing it. Also, when you do shave use a type of soap with moisturizer in it. That will help prevent stuble rash and in-grown hairs, and it will keep the skin nice and smooth.

Try Oil of Olay shower gel, I've had that reccomended to me. And a Mach 3 razor is good for this. And, as odd as it may sound, you might want to try some female shaving stuff, like a venus razor and some girlie shaving lotions. Because Men's shaving stuff is design for your face, but women's shaving products aren't design for other parts of their body.
