One thing an old person like me instantly recognizes about younger women: They consider sex as just something you do. There aren't a lot of preconditions and the like. Just do it.
Why does an old person like me relate to that? Because it was the same when I was young. Women had a hippie flair, and liked sex for the sake of sex. Far different from the "bimbo" attitudes of the 1980s that linger in middle-aged women today.
I think the change is refreshing, personally.
