That ACTION gave me a daughter and as was the custom of the day.......a wife!
My premarital shenanigans were the exception not the rule!
From my perspective 9 out of 10 is MUCH too high and certainly not indicative of 40's and early 50's, based on my experience and my geographical location!
You mean your "action" was IN the '40s-'50s?
This study seems to either cover or only find that people BORN in the '40s-'50s had just as much pre-marital sex as those later. I presume you were earlier!
And, see, I find nothing wrong with that. I know of lots of people with good marriages who played around and many who were pregnant at the wedding. No biggie.
