Yeah, it took me years (most of my formative ones) to realize that while it's all well and good to have women who really really like sex, that doesn't mean the women who Really Really Like Sex (particularly with the author's insert*) are the only women out there worth knowing.

I mean, seriously, RAH, your main character's mother gets the hots for her time-traveling son? Granted she didn't know until later but then she happily joins in with the all Heinlein orgy later on just because he's that awesome and so is she because she has the hots for him?

*Pun unintended but appropriate and therefore retained. "Time Enough for Love" was incredibly fun to read but a huge Gary Stu vehicle nonetheless.
