forgot to add this : https://www.mangago.me/read-manga/otonari_complex/ this one is great. feminine boy and masculine girl
Not adult, but slice of life: https://www.mangago.me/read-manga/company_and_private_life_on_and_off/
I still recommend it because both fl and ml crossdress and they have distinct fashion styles
out of curiosity, is there possibly any crossdresser male x female adult comics? if there is, any reco?
