If you want to have a lone-term relationship with a transgender woman, you need to accept her at first. Support her decisions, and always ready to live with a trans woman.
Talk about everything before dating
It means both you and your partner need to have a better understanding on each other, an it never means you can ask the trans girl some sensitive questions about trans. Great communication plays an important role in dating. Before dating a trans woman, you should clear that whether you can really accept trans women, and what are you dating for? For fun, for hookup, or for a long-term relationship. I hope everyone is serious in trans dating.
