Around the point that you're admitting to dating teenagers in your 30s and getting permission from mothers to date young girls, I feel like you start to lose any credibility regarding your behavior with girls only a couple years younger.
Using todays moral standards of course.....
Times were a bit different in the south in the 70's. Now I don't agree with it and if I were lucky enough to have a daughter I would never want her dating someone that much older than her when she was a teenager. However, to act like time period context doesn't matter is a bit off IMO.
