I tried shaving my diaper area once. I ended up with a rash that didn't want to go away. Then there was the itch when the hair grew back.

I've not shaved it since.
May I join the club? Jees-bees, I did that mistake last week. Still itchy. The condition is called folliculitis, the inflammation of hair follicles. I'll be happy when my hair grows back. Luckily it has started to do so already. BTW, shaving the pubic area and the associated risk of wounds and folliculitis also increases the possibility of abscesses forming. I once had an early-stage abscess in my groin. I was lucky to get is sorted out myself with a needle and hefty amounts of disinfectants.
As for the health benefits of having pubic hair: they actually protect the skin and act as pathogen snares -which is a good thing. They actually lower the risk of certain STDs (genital warts, for example) that may be transmitted by direct skin contact.
So, I'll stay with my pubic hair now on.
