Regardless of the term the attraction of older women to younger men is as old at the end of this system.
My only experience was as a 17 year old I went to my girlfriends house to meet up with her (before cell phones/texting) - her mum came to the door and said that she had gone out. Obviously our wires got crossed - mixed messages and wrong nights. She said she would be back in an hour of so and she said that she was sure that her daughter would be upset to think I came all the way (by bus) and went home without seeing her. I was invited in for a cup of tea, which seemed nice (my girlfriend was 16, her mum was around 36, and divorced). Well, I believe my hormones got the better of me, or perhaps she knew just how to fan the embers a little. Suffice to say, the rest can be left to your imagination. It was a bit odd when my girlfriend came home - we went out for a walk immediately, but never went back to her house. I broke up with her a week or so later, with mixed feelings. It was the start of summer holidays - they moved away before the start of the school year - I was never that fortunate again.... I never told anyone at the time, not even the girlfiend whom I met again a decade later after University.
While boasting about it one evening in the pub with friends, they remarked (including a few women) that it was more likely that the mother was protecting her daughter and made a bit if a "sacrifice" ...which fits....I guess....
