Here’s a story from a quarter-millennium ago called “The Female Husband” about a notorious lesbian of the era said to have married a woman while posing as a man. Some of the delicate phrasings are quite humorous:

As Molly Hamilton was extremely warm in her inclinations, and as those inclinations were so violently attached to Mrs. Johnson, it would not have been difficult for a less artful woman, in the most private hours, to turn the ardour of enthusiastic devotion into a different kind of flame.

Their conversation, therefore, soon became in the highest manner criminal, and transactions not fit to be mention’d past between them.

Or, how about:

Molly assured her mother of the falsehood of this report; and as it is usual for persons who are too eager in any cause, to prove too much, she asserted some things which staggered her mother’s belief, and made her cry out, O child, there is no such thing in human nature.
…
The whole truth having been disclosed before the justice, and something of too vile, wicked and scandalous a nature, which was found in the Doctor’s trunk, having been produced in evidence against her, she was committed to Bridewell.
…
At the trial the said Mary Price the wife, was produced as a witness, and being asked by the council, whether she had ever any suspicion of the Doctor’s sex during the whole time of the courtship, she answered positively in the negative. She was then asked how long they had been married, to which she answered three months; and whether they had cohabited the whole time together? to which her reply was in the affirmative. Then the council asked her, whether during the time of this cohabitation, she imagined the Doctor had behaved to her as a husband ought to his wife? Her modesty confounded her a little at this question; but she at last answered she did imagine so. Lastly, she was asked when it was that she first harboured any suspicion of her being imposed upon? To which she answered, she had not the least suspicion till her husband was carried before a magistrate, and there discovered, as hath been said above.

It sounds like pretty good use was made of “something of too vile, wicked and scandalous a nature, which was found in the Doctor’s trunk”.
