Highly discouraged, though my mum did take an afternoon off to tell us girls about condoms and how to use them, and she even showed us a female condom while she was at it.
I stole it and deformed it until it kinda looked like a sock. That got me yelled at (I didn't know it was so expensive and that my mum was planning to keep it to re-demonstrate if it was needed). I guess I was too young to find the idea of sex very interesting... as in something to actually do; it was mostly intelectual curiosity then.
Other than that, I got several "talks" about sex growing up. The latest was, I think, a couple of weeks ago, on the subject of women who don't insist their partners wear condoms.
Some of the talks were initiated by me or my sisters, some were from my mum.
Not as positive as you might think; when I was fifteen I timidly approached my mum with a hypothetical question about what she would do if one of her daughters turned out to be a lesbian... the gist: she was repulsed by even the idea, and said so in very graphic terms. Funnily enough, part of that speech included that she might be able to accept a trans, but not a lesbian (as weird as that sounds. She understands gender dysphoria, but can't grasp the concept of people being attracted to the same sex).
Needless to say, I never got far enough to tell her I actually fancied girls as well as boys. She still doesn't know. -_-
