No my parents never told me anything about sex.....I remember Mum saying that one or two of my classmates had been caught touching the girls "down there" and that I'd better not be doing the same thing - but I was innocent, in more ways than one. My parents clearly felt very awkward talking about sex. Years later when my father began to occasionally mention it (which he'd never do while Mum was there), I just wished he wouldn't. I was perfectly happy to discuss sex with my own peers, but the very idea of discussing it with parents or family was abhorrent to me. It was rather like swearing, which I guess carries the same kind of taboo.
I found out about sex from friends. They were the sole source of information because it was clearly dangerous to mention sex to the Big People. But they got some of the details wrong - two kids on our street thought girls had willies......in those days girls didn't wear tight trousers so there was no easy way of knowing the truth. Two more boys said they knew for a fact that girls had testicles I don't know who they'd been laying.
Anyway the data became more accurate over the years, and we eventually got a sex education lesson at the secondary school. They told us where to put it but didn't mention MOVING it......which could have been embarrassing during my first sexual encounter a year or so late - luckily my partner kind of moved her loins in the right way, and from my experience of masturbation (first demonstrated to me by another boy a few years earlier) I managed to deduce the right movements without ever having to reveal my ignorance.
The sex lesson was part of the biology course, which probably explains why they didn't mention the cliche about it only being OK between adults who love each other very much.....so I was never told that, but for some reason my sex life has never been very far removed from that maxim. Of course in those days it would have been much harder to find a girl who would go all the way until she felt the boy had grown to care about her, and after whinging about that for a year or two I began to accept it. These days I see a bit of sexual reluctance in a woman as a mark of maturity, though the world seems to be going in the opposite direction.
