-trim the area (short) first with electric trimmers.

-take a warm bath prior to shaving.

-you a new blade/razor each time. I recommend the gillette mach 3 turbo.
-decide whether you want to shave in the tub (with the warm water) or with shaving cream. Both ways work well.

-shave once with the grain to remove the bulk of the hair and once against the grain to smooth it out. Try not to shave any are more than 2-3 times to reduce the chances of razor burn.

-shave no more often then ever 5-7 days when you first start out.

-it is likely to itch at first, but this will go away after a day or two, and won't continue each time you shave in the future. Some talcom powder will help you to combat the itching.

-never use an electric razor.

-never use after shave.

-never use hair removal products.
