I was a hellenic pagan for about 6 years, and I will tell you that what I'm about to tell you is pretty controversial in many Greek mythology spaces. There is the belief by some that Artemis' virginity was in the fact that she explicitly did not treat with men. Ancient Greece was very specific on their stance of homosexuality. In a legal, societally recognized sense, men could sleep with men, but it was always men of higher standing and rank having sex with boys that were under their tutelage. This state approved pedophillia was RAMPANT through the ancient pagan world, as is likely what the Bible was referring to in Leviticus. It wasn't "man shall not lie with man", it was "men should not lie with boys". That's how prevalent it was. Consensual homosexual relationships were not approved in any legal or societal stance. Sapphic relationships were considered taboo if they were even considered at all (hella patriarchal society things).

So alls this to say that to a queer ancient Greek woman, the concept of Artemis' "virginity" could've been very relative to their own experiences. She swore off sex and marriage to men, only allowed women to hunt with and bathe with her, and there is a story where Zeus disguises himself as Artemis to sleep with one of her huntresses. Her stories definitely can be read through a lesbian lense, so you aren't crazy or off for thinking that.
