Dominantly sexually attracted to those of their own gender.
There's no way of knowing that. Possible to tell (to a limited extent) which gender they fucked the most, but that might not be the same thing (especially as you go further and further back, beyond the systems collapse out of which our own civilisation was, more-or-less, born).
You could 'scale' them. But the idea of having exclusively male/male partnerships is fairly modern. Not to say they did not happen, nor that they were not tolerated at any given time but it was a matter of necessity to have an heir. 500 years ago, I too would probably have married, had a child to secure the future of my estate then went back on discrete 'hunting' trips with the boyfriend.
And 500 years later, detractors would say 'oh no it was just a friendship' 'he had a child and was married blah blah' and others would say 'well if you look closely at his supposed friendship with x...'
Which really makes sexuality the play thing of two sides of the divide and the truth can often be lost.
