As a mear man why should I give advice, but I have found the best thing for shaving both my hair and my ex partners is a product that I have only found in "Wilkinsons" and it only costs £1 for 100 shaves. Look for a small plastic bottle called 4MEN.
I found from experiance of looking after my ex lady was after a bath moisten the hair and then rub 4/5 drops into the hair, and using a wet razor shave with the razor at a slight angle to the stroke of the razor, going with the hair.
rinse the razor after two strokes, continue until finished. Then sprinkle area again with water and shave again against the line of growth.
Result a smoth moisturised area that lasts twice as long as a normal shave.
