Can an amab genderfluid people who are sometimes men and present masculine mostly be lesbians? (Please no hate genuine question on my mind)

Okay I'm an AFAB nonbinary/genderfluid lesbian but I never feel fluid into the male binary. I am a lesbian in a lesbian relationship nonbinary x nonbinary both of us being lesbians leaning more fem than anything. This is a question that popped into my head like is that a possible thing? What if someone is persay a demiboy even can they be lesbians if they are amab? I dont want any hate i just cant find any info on thos topic.
