Um... have you ever used conditioner...

Maybe trim at a slightly longer length and condition the **** out of yourself! ... conditioner helps...

Whenever I wash the hair on my head, I shapmpoo 'down there' too, including a liberal coating of conditioner... I find it helps the freshly mown grass feel a bit softter to the touch - but if you have a number one, its going to be tricky coz there is nowhere for the remaining hair to go but straight out!
