Is my identity any less valid if I've never had sex with AFABs? tw: possible internalized homophobia.

I'm a ciswoman who has only ever slept with AMABs before, though I've slept with wayy more queer ppl than cis men. My mind has recently been telling me that I'm not actually gay bcos I've only been with AMABs so far, and I hate it. I know that that's not true, and that to even think that is transphobic as fuck. Is this some sort of internalized homophobia speaking? Idk.

But what do you guys think? What should I be telling myself? Sometimes my mind is my own monster.
