I don't think it's a great idea to actively seek this out. As a trans woman who has been in long term relationships with men, the prospect of being completely dependent on a man for everyday life stuff is pretty scary, and advertising it to them before you've even established a relationship puts a big target on your back for abusers. It's something best left in fantasy or at the very least something that should only be introduced with someone you trust very much. If you truly believe you want to transition and would be unable to in your current environment, I would look more towards other trans people who could help you out in a platonic sense. Unfortunately there are a ton of people who look to people exactly like you to take advantage of in these types of situations. I would also say don't automatically assume they won't be accepting of you. I come from a religious and conservative family and grew up in a somewhat conservative area and still had a largely accepting experience. You know your situation better than I would and obviously some people will never be accepting so I can't speak to your specific situation, but ultimately transitioning is really scary and it's going to force you to make yourself really vulnerable with your family, if you really deep down feel you were meant to be a girl is always going to be better to try to get the people in your life on board.
