I came out as trans to my partner a short while ago. She’s bisexual and I figured she would probably be uncomfortable at first and then come around to the idea once I’d ironed out some of the details of how I planned to transition and gave her some time to acclimatise.
However, it turns out she’s bisexual not biromantic and has additionally never found trans women attractive (despite having trans friends and at least two exs that came out as trans after the fact). When i told her what i want from medical transition she said that the thought of me changing anything about my appearance made her really sad and that she didn’t think she would be able to find me attractive.
She likes my beard, body hair, voice, and overall shape. Precisely the things that are the biggest source of dysphoria for me. And while I don’t have any genital related dysphoria, she’s been reading about shrinkage due to estrogen and is 100% not ok with it. I’m not saying she’s a size queen, but she wants it fully functional and at full capacity, I’m ok with giving her that if it were possible but it’d be more for her than me.
I know I really want to start hrt ASAP, but at the same time I can’t deal with loosing her. We have a family together and she has helped me through some very difficult and dark times in my past. We are living thousands of km from our families and neither of us can afford to raise the kids on our own. I have no friends because of moving around a lot and family obligations. Aside for my love for her, I can’t go through transition without an understanding adult in my life (IRL) who I can lean on when things get difficult.
She keeps saying that she wouldn’t feel right trying to prevent me from doing it, but the thought of not being with her is crippling.
What do I do?

No I get that I’d just keep being miserable if I don’t transition. And my partner really wants to be ok with it and wants to be there for me but she’s worried she’ll loose attraction.
I know I’m probably going to end up starting at some point before summer. I’m just worried about it. We’ve been each others entire world for almost 2 decades. And neither of us really has other family. Her mother will probably die within the year and both my parents would probably disown me if I transition.
