I am a transman and honestly I haven't had a hard time dating. I always come to question my partners the same questions you are asking, some said before their answer is no, some said they did not close their doors but I think you are right, it'll just happen. You will just fell in love and that's it, no matter what the gender is. If love hits you, it will hit you so hard. Regardless. You will come to accept your partners gender preference. But the biggest hindrance is the society. What others will think. What their family, their friends, community and even what the social media world will say. Especially here in my country, Philippines. The LGBT community here started something but I think they would have to work longer to educate more people here. Sucks but that's how society works.
