If this is the first time she shaving and she has a bushy pussy,
I suggest cutting the longer hair with a scissors first. When I
first start shaving I used a small manicure scissors. It gets closer
to the skin.

Then use a good shaving gel, and a fresh blade in you razor.
If you use a disposable, make sure it fairly new. ( A dull blade is
sure to cause itchy stubble.)

Finally, after shaving I use a moisturizer for dry skin. I use
Lubridrem, but any good dry skin moisturizer would do !!!!!

Hope this helps !!!!!!!
