Why does the older-man/younger-woman preference get no respect?
The knee-jerk response for most women is, "Ewwwwww," But it's considered politically incorrect these days to feel and react that way about gays, lesbians, bi's, transsexuals, cross-dressers, she-males, etc, etc, etc. Look. It isn't even listed here as a part of this group. But the older/younger scene is no less compelling for those who desire it. The world has some growing-up to do in this area.
Oh, and let's not forget the "cougar" version. See what I mean?
Yeah, there is the sugar-daddy/sugar-baby thing. That is simply a practical arrangement. I'm talking about a different sort of legitimate, but still ignored, sexual orientation.
