Yeah, but my point was that a female human does not have to be an adult to be a lesbian. Girls who aren't adults can be & are lesbians.

Only a woman/girl who loves a woman/girl is a lesbian

But to be a lesbian, it's not necessary to be a female human who "loves a woman/girl" or to be engaged in "loving another adult female" like the previous poster said. All that's required to be a lesbian is to be a female human who is exclusively sexually attracted to other female humans. Many lesbians have not found "a girl/woman to love" nor are they actively engaged in "loving" another girl/woman. But they're still lesbians if they are female humans solely attracted sexually to other female humans.

Also, since lesbians are human like everyone else, there inevitably will be/are some lesbians who are not capable of love/loving.

Male homosexuality is defined as exclusive sexual attraction to other males. Males are not required to have one particular same-sex love interest or to be engaged in "loving" relationships to be considered legitimately gay. Same goes for het people: no one says that in order to be considered heterosexual a person must have found someone to love & to be engaged in loving them.

Requiring a female human to have found another individual to"love" & be "loving" to be in order to be considered legitimately lesbian is a double standard. A sexist double standard that says lesbians' sexuality is real & "valid" only if they have an intimate partner/love interest with whom they are besotted/head over heels in love and are actively (or passively) engaged in loving, but that places no similar requirements on gay males, or het and bi people of either sex.
