First of all, the word lesbian actually comes from the Greek Islands of Lesbos where she is born, as a slang term to describe female on female sexual and romantic relations. In fact, it wasnt even until the late 19 century where the word has the meaning it has now. I seriously doubt they(lesbian of lesbos) had any say in how their word is used in modern terms(especially since it's a heated debate of topic for the island to this day).

I am Greek.And you are correct.Inhabitants of the isle of Lesbos can not use the term lesbian anymore as an adjective of origin (and often avoid calling their island Lesbos they call it Mytilene,the name of their capital city instead),because it was hijacked by foreigners to denote a sexuality.They had no say on that and they are very angry about it.

I use the term homosexual woman for myself,both for clarity and to give my compatriots a break.

but a woman who engages in consentful sex with young male lovers is bisexual in my book.
