Sorry for this,
I remember my wife being told as a preteen that the way to get your boobs to grow was to get a guy to rub them. She told me for weeks her and her sister would pick up their baby brother and rub him across their chests. They both developed boobs so it must be true

Remember guys, as we girls have to remember, is that puberty takes a long time. Some XY males never develop much facial hair, others cannot stop it growing. It's to do with genetics and T levels. "They" say that we girls develop about one size smaller than our genetic sisters or mothers in the boob dept. I'm not sure if that holds true in the male line as well as far as facial hair, never seen a comment on it too be honest.
Hugs Guys, and you are welcome to shaving the face. Mmm I do more shaving as a girl as I ever did as a guy
