No no no, that's what it's supposed to be like, the idea that some celebrity is more attractive than a normal woman is what the magazines want you to believe. The reason people are given to finding them attractive in a wholesale kind of way is because their bodies are presented as a clear focus of any picture or style of dress. Therefore their physical attributes become a target for "displacement" of their high social status, which is what admirers really find attractive.
Not to mention the matching hypothesis, which says we are most attracted to people who are in the same league as us, doubtless because of the increased possibility that the fantasy might become reality.
Finally, watching porn and admiring good bodies is so hugely far removed from the experience of real-life sex that it's a complete fallacy to compare them. I might like to look at stunning people, but if I was actually in bed with them I wouldn't have a clue what to do.
For example, take Lovefoxxx93. I have always preferred girls with supposed skin imperfections such as acne scars and freckles.
I suppose there is also a certain sexiness about knowing about someone else's imperfections which they cover up from the wider world.
