Hi all, I'm brand new to this board, so please bear with me.
For a little bit of background to my problem, I'm a 26 year old female and internally identify as male. I don't plan on or intend to transition, but I do dress as male and am often confused for a male. I remember having dreams when I was about five years old that I was born a boy, but my parents surgically altered me into a girl (didn't actually happen). I'm now dating a girl who had never been with a girl before me, and still identifies as "straight" even though we've been together for almost two years. She says she doesn't see me as being female, but not male either.
My girlfriend is a very beautiful woman and often gets attention from actual guys. This has brought up a whole bunch of insecurities that I didn't even know that I had. Every time she gets attention or some guy pursues her, I feel like I'm going to lose her to him because I'm not male and so I can't compete with him. It's stressful and tiring to constantly be worrying and feeling like I'm not good enough because I wasn't born the way I feel inside and not the gender of partner that my girlfriend is used to. She reassures me that she's not interested, that I don't have to compete for her because I already have her, and that she wants to be with me, but for some reason it just doesn't feel like it. This has caused a strain on our relationship because we are always fighting about this.
I don't know what to do to not feel like I'm less of a partner because I'm not male. If anyone can point me in the direction of resources to deal with this, I'd be very grateful. I don't have much income right now so counseling is out of the question unfortunately. Thank y'all in advance for any comments/suggestions.
