Mostly with you there, except that I believe that some things should be explicitly explained; particularly around the area of consent. A lot of mainstream porn is a bit rapey for my personal tastes and there's quite a few things that are fine in porn amongst consenting, paid professionals that should not be imported into RL without everyone involved being happy about it. Surprise arse-slaps; slapping someone around the face with a cock; grabbing people's heads and ramming the cock in...that sort of thing. Good communication is the key here because in RL you haven't seen the script.
Also anal sex should be well-lubed and a cock shouldn't be the first thing in there, for example. If you believe the porn flicks and just launch yourself in there from the wardrobe then you can do real damage.
Also, some positions should not be attempted if you are prone to bad backs. Trust me on this.
Arse-to-anything is a really stupid idea. There's some truly disgusting diseases you can pick up that way.
And so on. While I'm sure that on one level people do know it's a fantasy; beginners won't necessarily know which bits are a good idea to imitate and which bits should definitely be left on screen. If the government wanted to actually help, they should produce a non-judgemental information site that goes into detail about this. Instead, they legislate an actually harmful spreading of ignorance. I despair at times.
Also, porn stars bleach their arseholes, so a quick note on realistic expectations might be helpful, too.
