At the risk of repeating what has already been said several times:
Sex is very personal and while we're having it we're very vulnerable even though we may be having a fabulous time. It's intimately tied up with our sense of self and a large part of it is subconscious. Start trying to explain in depth why you like your particular sexual fantasies for example and most people find it very hard.
Most social influence is subconscious. As a result of it, we all do things that we may actually disagree with on a rational basis. Most women get annoyed about the endless photoshopping of supermodels and celebrities and are saddened and angry about the fact that anorexia is rife in the fashion world, etc. Rationally, we all condemn it. Yet the vast majority of us who will make these arguments still worry about our weight and try to conform to social standards of beauty at the very same time we bemoan how unhelpful these practises are.
That doesn't make us lesser people. It makes us influenced by society. Because the truth is, most people suffer if they fail to follow those social norms. That's which is how society works. For every Susan Boyle out there there are many more singers with voices like hers who have failed to get anywhere because they don't have a body like Rihanna's, for example. Women suffer if they don't conform. That's proven fact. Similarly everyone decided to take what they want from the supermarket without paying, for example, there simply isn't enough police to stop it. But the reason it doesn't happen is because this would be a socially unacceptable thing to do.
Some of the posters on this thread who have argued against this strap being available in AS may actually use it themselves. It's possible to do something and enjoy it while at the same time recognising that the wider implications have harmful significance. It's no reflection on you as an individual; it's an analysis of society. It's only because sex is so personal and so rooted in our sense of who we are that people react so defensively to this idea.
