hihi anon!! i really appreciate your question and respect in asking, i’ll do my best to answer in a good way!! i’ll break down all of my identities separately and then tell you how they interact with each other, i hope that works!! lmk if you need more explanation!
-transmascness: i identify as non binary, but masc leaning. i do not identify as a “woman”, which does somewhat alienate me from c1s lesbian spaces because of the fact i don’t identify as a woman. but as long as i and the important people in my life understand this, i am okay with that. i fall under the “non man” definition of lesbian
-aromantic: i do not seek nor wish to seek romantic relationships, and i don’t feel romantic attraction. to me, my platonic relationships are more important to me. so i do not engage in lesbian relationships romantically ! (my exact identity is “demiromantic”, in the sense that if a romantic relationship happens, then great, but i don’t actively seek it, and can’t form those attractions with people who i’m not close to first)
-asexuality: this one gets a tad more complex, so i do apologise if this doesn’t make sense. i do not feel sexual attraction, unless i have a pre-existing (usually platonic) relationship/bond with that person. for example, im very sexually attracted to two of my friends where we’re in a sexual-based relationship (obviously alongside our existing platonic bond). BUT, i still engage in sex based relationships with other people i’m NOT attracted to. i more so am attracted to the feelings of sex, because these actions feel physically good. this overlaps with my lesbian identity because i only engage in sex based relationships with people who don’t identify as men. i do not enjoy sex based relationships with men, i’ve had too many bad experiences with men to enjoy them. my transmascness affects my relationship with men who are sexually attracted to me because they usually view me as women, which makes me uncomfortable. and i’ve had too many men not respect when i say no. and i just don’t feel good when i engage with men in that regard (it’s not their anatomy)

i hope this helps or explains it? all in all, labels should only serve you in ways that make you feel good. labels only exist to help explain our relationships with others, if you feel boxed in then you needn’t use a label <3
