If she's a smart girl and you have a good I don't think you need to worry OP. But I can see why you're concerned.
I clearly remember hating Jackie magazine at around your DD's age. I remember an interview with David Cassidy where he apparently said he didn't like girls who wore make up.
At 12 I thought that was a bit odd. Now I know about David Cassidy's indulgences - perfectly normal for a very good-looking, incredibly famous young man - it seems like nasty moralising and mind control.
The Cathy and Claire problem page used to have at least one letter a week from a girl who wanted her boyfriend to go 'all the way' but that he didn't want to.
Yeah, like that was likely rather than the other way round. The answer always used to be along the lines of 'shame on you, slut. You should be grateful to have such a nice boyfriend.'
Weird. I later met someone who'd worked on Jackie and she confirmed that it was all completely made up and there was a definite agenda from the publishers to keep girls pure.
I loved it when My Guy came out and they had realistic problem pages that talked about body image and spots and the pressure on you when you were a 14-year-old virgin and all your friends claimed to have done it.
One teen magazine even had Position Of The Week. It caused outrage in frothing about girls' magazines in the early 90s. I too old to read it but I don't think it was too bad to have a frank discussion about sex and whether you want to do it or not.
