That magazine stuff was nowhere near as strong as what can now be seen on the web. What I saw (Playboy, Penthouse etc) depicted the girls as graceful, virginal and as inaccessible as marble statues.
As for being "relatively normal", what is your benchmark ? Sexual practices have changed enormously in a generation - what was normal then is not normal now, and vice-versa, for better or for worse I'm not saying. In that time gay sex and anal sex have been legalised, high-street brothels have become commonplace, escorts advertise widely in the local paper and on the web, and dating sites advertise on TV. I would suggest that some of the change, if not most of it, has been driven by harder pornography.
One effect of seeing beautiful girls (the likes of which I never had the luck to meet in real life) being shagged (usually by revolting old men) is maybe to make men open their eyes to possibilities, be less satisfied with their own GF's/wives, and to realise that such girls can be found and can be bought. Then maybe to visit escorts or brothels themselves - hence the increased number and higher profile of them. Certainly those girls do interesting things that my wife would never do; it's tempting I must say.
