Re: Depressing...
"Depressing" is about right.
Not the article and not the research, but the field that this may have solid value in - depression.
We have just had a nice rant about homosexuality in the comments section of an article about Putin-vs-Cook and one thing I mentioned there is that LGBT adolescents are some 4-6 times more likely to commit suicide than their heterosexual counterparts.
Sex and sexuality has long been a cause for anguish in many. It seems that there are still far too many taboos that have no place in rational society and as a result far too many people are left feeling that they are 'weird' or 'wrong' and many more are simply too scared to share their fantasies or desires with their partners.
In some ways, the Internet is actually a great boon for some of these people due to the much-referenced 'rule 34', which, loosely translated, can be interpreted to mean: no matter what your sexual fantasies or desires, you are not alone.
Not wanting to actually pay for the report, I wonder what constitutes 'common', 'unusual' and 'rare', however.
If 'unusual' is one in one hundred then even though that is, clearly, not a large percent, it would still mean what when you go to work in the morning, one person on your bus* will enjoy being urinated on or urinating on someone else and, should you enjoy that, you could walk onto a peak hour train in Sydney and find someone who might enjoy sharing your fantasy without having to change carriage.
Perhaps that specific fantasy is not quite that common (I have no idea - it could be) but you get my point - given the number of people we interact with and see each day, even relatively 'unusual' sexual behaviours and fantasies are never that far from us.
Which is kind of a good thing, reminded as I am of an amusing song from my younger days.
I just hope the term remains "sexual deviation" rather than "sexual deviancy".
* - Obviously it's nowhere near that neat in practice, but that's just to get an idea of this in human terms.
