So what exact porn moves is she talking about? I watch a fair amount of porn, and a lot of the positions are obviously uncomfortable and just for show. Even if it wasn't obvious at first, it would be as soon as you tried them.
However, I do think porn has introduced me to some new, valuable ideas. Maybe this lady has just had some bad lovers? Anyway, while I think the rationale is condescending, I'm all for some more "natural" looking porn on the market.
