Here are some interesting facts on that topic. Specifically to section 4 on homosexuality. I will quote a section of it:
Yes. I googled medieval sexuality. Get over it.
Oh, certainly people had homosexual sex with each other in the middle ages . . . however, they probably didn't identify as homosexual as such (though there is some debate over this). Regardless, it was not generally well looked upon and didn't happen out in the open, since as that same section points out, it was viewed as being wrong and had strong punishments attached to it (though tolerance did vary from time period to time period and place to place, but to my understanding, it was never completely 'in the open').
My objection stems not from it happening in BM, but from how it is usually portrayed in BM. If you're going to do it, sure, but do it
right.
