how did yall find out you were lesbian?

t a ounce of attraction towards men, until i met my ex bf who is trans, i didn't like to have sex with him but i kind of forced myself to, i bled a lot during it, for this reason i thought i was lesbian, but i met my ex bsf (trans man) and i felt rlly attracted fo him, sex was ok bc i got wet and it didnt hurt also i felt rlly comfortable w him, i used to get jealous ab him, but now idk if i even liked him romantically, i feel like i only felt rlly comfortable w him and didn't mind the sex, i only felt attracted to these two men in my whole life, but i feel sick only by touching a cis man, idk if im a lesbian or not, im scared of being transphobic i rlly dont know (english is not my first language, sorry if i was disrespectful in any way shape or form, if i said something wrong pls educate me in the replies, im just rlly confused idk) i also do not know how to label what i felt for these two men, i don't know if it was a rlly strong feeling of friendship i felt towards them, bc i was bsf w both before, i do know i had a lot of gender envy towards them
