That’s the term which would have been socially appropriate at the time, psychonaut. In the case that was most famous in Spain, the information we have indicates that the lady Doña Catalina de Erauso almost married had no idea she was being courted by a biological woman: how do you call that? Doña Catalina was transexual, but she was also posing as the only kind of man her culture knew, which was biological ones (she eventually came out, later obtained permission to dress as a man, and continued dressing as a man and using diverse male names).
And the “producing children” is not because OMG we wuvvv children!!! I mean, I don’t think your average medieval person disliked children, but both marriage and legitimate children were important to the continuation of family and the stable transfer of property and other assets. In Europe, at least, gay marriage would have been not only pointless in the long term, but wicked. Geoffrey of Gayland deeds his lands to his husband, and when he dies it goes to the husband’s family, not Geoffrey’s.
The institution of marriage has already changed beyond recognition in that it’s not really much about the intergenerational transfer of property, but about what happens while you’re still alive. If you have assets, you make a will or create a trust.
Just because bigotry and ignorance was socially appropriate once upon a time doesn’t mean it’s acceptable to ape it today. I can think of lots of now-offensive words to describe black people which were socially acceptable 150 years ago, but I wouldn’t use them today even to refer to someone from that period.
