Sapphics, I need your wisdom: are bisexual lesbians...valid? A thing? Bisexual lesbian feels like an oxymoron idk but I keep seeing discourse and this is....far outside my sphere

Lesbian just feels like a very specific term and I think labels should mean things but also ????

So I asked some irls and the answer seems to be: it's complicated but the short answer is no, you cannot be a lesbian and be into men
