Of course Foucault did. My understanding is that it was a longstanding custom for French men of means and learning in the colonial era and afterwards to travel to North Africa and the Middle East looking for boys and girls to fuck, or both. Including Gustave Flaubert, author of Madame Bovary who once (in) famously said, "It may be a perverted taste, but I love prostitution, and for itself, too, quite apart from its carnal aspects."

Letter from Gustave Flaubert to Louis Bouilhet from Cairo, Egypt 15 January 1850 about seeking out sex with bardashes (homosexual males):

Speaking of bardashes, this is what I know about them. Here it is quite accepted. One admits one’s sodomy, and it is spoken of at table in the hotel. Sometimes you do a bit of denying, and then everybody teases you and you end up confessing.

Traveling as we are for educational purposes, and charged with a mission by the government, we have considered it our duty to indulge in this form of ejaculation. So far the occasion has not presented itself. We continue to seek it, however.

It’s at the baths that such things take place. You reserve the bath for yourself (five francs including masseurs, pipe, coffee, sheet and towel) and you skewer your lad in one of the rooms. Be informed, furthermore, that all the bath-boys are bardashes. The final masseurs, the ones who come to rub you when all the rest is done, are usually quite nice young boys.

We had our eye on one in an establishment very near our hotel. I reserved the bath exclusively for myself. I went, and the rascal was away that day!

Flaubert to Louis Bouilhet Between Girga and Assiut 2 June 1850

By the way, you asked me if I consummated that business at the baths. Yes – and on a pockmarked young rascal wearing a white turban. It made me laugh, that’s all. But I’ll be at it again. To be done well, an experiment must be repeated.

Flaubert to Louis Bouilhet Constantinople 14 November 1850

We walked through (no more than that) the street of the male brothels. We saw bardashes buying sugared almonds, doubtless with money earned by their arses: the anus was about to supply the stomach with the nourishment the latter usually furnishes the former. From ground-floor rooms came the shrill sound of violins: they were dancing the romaïque (these young boys are ordinarily Greeks: they wear their hair very long).

BTW, IIRC Flaubert on the witness stand in his obscenity trial over Madame Bovary testified that (paraphrase and translation) "Madame Bovary is me! I am Madame Bovary!"

Clearly, Flaubert must've been a transwoman. Someone alert Grace Lavery.

Wow, that sucks. :( Discipline and Punish is still a great book though.
