I have seen limited indications that some older texts use lesbianism and lesbian to denote the practice and respectively practitioner of oral sex regardless of gender, and that some other older texts use the words to refer to what would now be termed bisexual(ity). I may try to find citations and add these senses later. For now, one which was brought to my attention was Rosenbaum's Plague of Lust, "one who with the lips or the tongue performs the office of rubbing and sucking another's penis to follow the Lesbian mode"; this is capitalized and mentions "Lesbian" as a translation of a Greek name for the practice, so is not a good cite, but is suggestive that other cites may exist. In turn, the other sense would be a reference to the argument that Sappho was into both men and women. (This page, incidentally, seems to have a use of bisexual in its now-rare sense of intersex/androgynous/bi-sexed.) - -sche (discuss) 18:30, 2 July 2019 (UTC)
