Then there is absolutely no difference between a 14 yo boy and a 30 yo boy either, other than the 30 yo is fast approaching the brick wall.
Oh wait; yes there is, a huge difference. Teenagers (regardless of gender) are children, 30-year-olds are adults.
We definitely do NOT need to see children as adults. Women reach their mental peak around 25-65 (as women are individuals and peak at different ages). Women were never intended to reproduce before 18 or so, as the hips are not ready for childbearing until then. If anything, women (and men) mature earlier now, with better nutrition, than they ever did throughout human history.
Are you sure that you're thinking about real 14-year-olds, and not the adults portraying 14-year-olds in porn, honey?
Here's a random 14-year-old from the Net. Does she look like she's ready to be a mother in 9 months?
[Oops, huge picture. Will look for smaller...]
I'd say YOU are the perpetual teenager, VE, as you apparently can't grasp the fact that women mature, and keep on maturing, even after age 30.
VastlyImbecilic is more fitting, dearie.
