The insistence that we’re all bisexual really is being taken as some great revelation about the human condition. Whereas, among those who have met actual humans and considered their behaviour, it’s very old hat indeed.
No, this is not to say that we’re all equally likely to be wandering Hampstead Heath in search of a little cottaging. But a useful definition of near all humans is that we’re really, really, interested in sex. Because, and for pretty much no other reason, we’re descended from those who were really, really, interested in sex. That being how this evolution thing works. Yes, of course, only one variety of sex leads to that progeny but the drive, the over-ridding one, is for the sex, not the form.
There is no explaining public schools nor prisons – to the extant that I am not repeating myself – without grasping this point:
Strictly heterosexual people don’t exist, according to a psychologist who claims more and more men are better defined as ‘mostly straight’.
While most societies promote heterosexuality as the ‘norm’, a leading researcher at Cornell University has found most of us get aroused by both genders.
The paper brings into question strict definitions of sexuality, and posits that instead of categories we should see it as a spectrum.
If there is no such thing as pure heterosexuality then there’s also no such thing as pure homosexuality. Something that is less likely to be said these days given social fashion but they are in fact the same statement. Human sexuality is that spectrum, we all lie at different points along it and our position at any one moment in time depends upon the opportunities available to us. Some will choose one thing more than another but change the incentives and we will, as with near all other things humans do, change the behaviour.
Entirely male societies do have more incidence – sorry, often do – of male on male sex than more gender mixed ones. We would assume the same of all female ones.
Note that the existence of this spectrum still allows for something like the vast majority not to act out in anything other than a heterosexual manner. For given the incentives we do have in the society around us people do tend to end up doing what they prefer rather than being driven by circumstance into something they’re not all that keen upon. The usual numbers are that some 10-12% of all men have ever had a same sex experience. Thus, despite agreeing upon the existence of the spectrum we’re also saying that 90% of men are, in action, heterosexual.
