if you feel a longing when looking at all of those things i feel like it is safe to say you have some gender dysphoria. maybe you always have and you were just very repressed and able to ignore it until directly confronted with hte topic of trans men and their transition.

its normal for people who are trans to do this, and even its normal for people who are very gnc but cis to do this. whatever you are, you should really really find a gender counselor to speak to. they are the best option for you, they can help talk you through everything you feel and experience and help you come to the conclusion on where your gender identity lies.
