I'm conflicted on the matter. I'll explain.
Most people are experienced to the point that they've seen pornography and have probably masturbated before they ever have sex (or engage in sexual contact) with someone. There's fascination & excitement, but no 'wonder'. In most cases they're not seeing something for the first time, and they generally know what they're getting themselves into. The blissful ignorance going into sex is something that is forever lost to us -- we can no longer be pioneers of our own bodies, as the information is out there and readily accessible. I know what I mean.
Then there are the social consequences.. the obsession with size, vocal (usually faked) orgasms, a standard of behavior, etc. When a guy or gal whose only experience in the area comes from porn tries to envision sex, it's inherently (and probably permanently) influenced by the various actors & actresses they've seen banging away at each other. Girls who see women in both pornography & mainstream Hollywood experiencing fantastic orgasms are naturally let down due to the inexperience of their partners.
The preoccupation of society with sexual performance mirrors that of our desire for perfect sex symbols (Actors/Actresses, Supermodels, etc), which is directly contradicted by the rising numbers of unhealthy & obese people in the world. Both sexes generally fail to live up to the expectations of the other, and those who succeed often die young because of the health hazards involved -- anorexia, HIV/AIDS..
Oh. Wow. I kinda got off on a tangent there.. I'll stop.
Simply put, the sexual freedom that porn has given us has come at the cost of increased sexual/societal pressure.
