It is very interesting, thank you for posting it CrispyFern. I actually identify with some of the article, having had my fair share of bad and even painful sex that were categorically caused by my own issues, not the actions of my sexual partner. I participated, I even feigned enthusiasm - they were not to blame in any real sense. I think that I fell victim on more than one occasion to the conflicting society messages in respect of female sexuality - that I was at fault for not enjoying it because I was not sexy enough perhaps, that I had gone to far to stop the action, that actual enjoyment of sex is a male preserve and nice girls don't say 'that feels bad do it like this'. I lost my virginity very young and spent a good few years have shockingly awful sex because I felt as though I should be having it, not because I actually wanted it. I say this now with the benefit of hindsight - I did not realize it at the time by the way.
I cannot be sure of it, but I think that this is a uniquely female issue. I don't believe men, the possessor of the penis will ever quite understand the vulnerability that comes with being entered by another person. Sex, good or not, requires a woman to give up something each and every time. The wrong mindset and the inherent patriarchy of pretty much all sexual propaganda can combine to ensure that good sex is a bloody myth rather than a right.
