what does being lesbian mean to you?

a while ago there was discourse on people who identify as bi lesbians, as in biromantic lesbian.

some people said that bi lesbian was invalid because being lesbian meant there could be absolutely no attraction to men, but some people said that because of the spilt attraction model, bi lesbians were valid because one’s romantic attraction doesn’t always match your sexual attraction. i always thought ”lesbian” meant homosexual woman, so didn’t really see why bi lesbian wouldn’t work, but wanted to ask lesbians before i decided.
