the good ole days of banging 12 year old girls in your parents room
I think this is what leads to pedophilia... among other things.
it's guys that never got pussy when they were young.
like for most kids it was normal at some point to start playing doctor with that little blond girl who lived down the street. the whole "I'll show you mine if you show me yours" in the backyard. mostly out of curiosity, because you weren't old enough to really be horny. but then hormones started flowing and the dry humping started. you just wanted to hug her, you still weren't sure why. one thing led to another and suddenly she wanted to give you a handjob and you wanted to finger her snatch.
most guys will have already gotten over the immature pussy and learned to appreciate and seek out a grown woman. natural progression. but guys who missed out on young pussy when the time was right (like when they were
also young) end up seeking it out when they're older, thus planting the seeds of pedophilia.

oh, and as for bush hair, I think it's pretty natural to want to keep it trim.
easier to clean, easier to play with. goes for men and women.
