Im 16 and have been shaving ever since I got hair down there.
I absolutely hate every form of body hair.
Personally mine has never been soft since and I don't remember it ever being since I was so young.
Personally If you shave everything up to the pubic bone (or area thats exposed when your naked) Its fine but if you shave that patch you will get red bumps, it is very pain full and itchy.
I personally wax that area and shave the rest.
But I can't stand the itch when it grows back so this weekend Im getting laser hair removal

hope that helps
