I was somewhere between 12 and 14 (ish) when I discovered (some of) Heinlein's novels, along with the (still very good) story collection, The Past Through Tomorrow, which packaged most of his short Future History stuff).
What you've said about Time Enough for Love pretty much parses with what I remember of it. That said, around the same time I also read Farnham's Freehold. The latter is probably a better novel qua novel than Love (or Friday for that matter), but a story set in a future in which Black Folks have taken over America and gone about killing and (someone correct me if I'm wrong; it has been more than 30 years) even eating the White Folks is a wholse 'nother kind of problematic.
Worst? Maybe not ...
