Yup, it's especially funny because the present-day, deeply egalitarian idea of homosexuality (with its attendant developments, including gay marriage) is a very modern (late 19th c. at the earliest) development. Back in, say, Ancient Greece and Rome, "prison bitch" was all you got - both homosexual sex and, to a large extent, heterosexual were essentially predatory in nature. Rape culture was very real. (You can see the consequences of this e.g. in the Christian new testament, where the homosexual practices of the time are said to be an abomination but this also extends to heterosexual practices.)

(OP's article does attempt to reframe the typical practices of the time and make them "fit" the modern egalitarian view, but note how even in their own account it's always the older, more dominant member of the pairing who is said to "love" and "care" for his younger and more submissive partner. This is clearly the same sort of highly skewed arrangement that is well known from ancient Mediterranean cultures.)
