Oh, I'm sure of that. As I've said before, the times that I grew up in were somewhat different, so I don't find this idea as shocking as many of the guys here who grew up later. My niece got married when she 15 (and is still married over 30 years later). We've talked about Jerry Lee Lewis marrying his 13 year old cousin, and rock stars having sex with 14 year old groupies. Elvis became attracted to Priscilla when she was 14. In 1969, Eric Clapton's band Blind Faith featured a picture of a topless 11 year old girl on its album cover. I'm not sure someone wouldn't go to jail if this happened today. Or is this still a protected act because it's "art"?
When I was growing up, this sort of thing was much more common. I think largely because feminism had not fully taken hold yet. In my day, the message feminists were putting out was that women should have the choice of having careers, or to be housewives - but that there was no shame in being a housewife. Now days, that "housewife" option seems to be largely dead - most families need two incomes now, unless the man makes very good money. And most women are expected to put off having a family and go to college instead.
Anyway, I think the age that girls become viable sex partners is largely an artificial construct of our current society. Biologically, girls are clearly ready for sex well before the age of consent of 16, 17, or 18. The culture artificially extends childhood by an education system that can keep a human until almost a third of that person's life. Is this really the most efficient use of our time?
