Are you on HRT or presenting as female? If either, and the HRT is working, then yeah, do it, maybe. But, if not, and you only are female inside and your outside doesn't match, people can't be expected to deduce that. One day, being miss'd or ma'amed will be second nature and this will all be moot. I can't remember the last time someone called me sir without apologizing once they saw my face. But, really, being gendered correctly is awesome, but once you walk by guys and they say "that bitch has a banging body, when she's an older and not in college, she's gonna be the ->-bleeped-<-..." or They just put their arms around you or touch you or do this or that. it starts to get old and degrading. I was shopping today with my BF and he bought me this uber cute hoodie and the guy wouldn't leave me alone and kept telling me what a beautiful woman i am. Creepy. But girls are being super awesome to me and the last couple days I have been checking my hair and each time some woman came up to me and said, sweetie it loks great. You're so lucky you can pull of short hair like that. Most women can't. You're rocking it." So that was awesome. But, that intial feeling, first being miss'd....amazing. You'll get there don't let it get you down. I never thought I would but here I am not even able to pass as male or even trans.
