I agree 100%. I crack a lot of off-color jokes here, but seriously, you are right. I have found that it depends largeley on where you meet the girl, and in what context the dating relationship is started.
I lived an absolutely hedonistic, sex crazed life for a couple of years, before I got saved. I met my wife 18 months later, and she was no angel beforehand either.
My wife and I also abstained during our 10 month engagement. (We couldn't go 1 1/2 years, that's crazy! lol) We have been together for 13 years now, happily. The 'old wisdom' works.
Yes it does. It not only works, but is vastly superior.
