trim it first......the decide on how you want the cut style, a strip a triangle and arrow type thing, or all bald. to me i like to keep alittle womanhood witha stripe. ......start shaving in the direction of the hair growth first then against and always finish by closing the folicle (witht the hair growth direction)   .......its easiest in the bath tub for the first few times till you get a feel of it......dont be afraid to use your finger as a guide or to steady the skin still either.     but once you start it impossible to stop,, so for the first time i would say just trim it and get used to the feel, then later make the decision.    also be careful about putting lotion on i suggest olive oil if you get irritated or dry
