I can relate to how you feel. I'm amab and romantically attracted to women. However, over the years and especially over the past 5, I've desired to present and be identified as a woman. For me personally, I'm still in the closet to all but a select few, but I've grown my hair quite long, have kept as clean shaven as possible, and have been slowly adding more clothing to my wardrobe that suits how I feel. I have also felt guilt on being in a relationship not knowing if my partner would be accepting of dating someone who's at least gender-fluid or at most, closeted trans-woman. Confidence is something I'm actively working on improving.
However, the most important thing is that you are happy. Whatever people may say or assume, only you can definitively say who you are, not others. There are people on this board and in the world as a whole that are accepting and will be more than willing to accept you for how you are! ?
