I'm sorry, I'm not a man, but I do know the answer to your question. Disclosing your trans status in a dating profile is guaranteed to attract chasers. Once they realized you wanted a relationship and not just sex, they probably lost interest. I can almost guarantee it's not your fault, there's just a lot of gross men. You are a woman, it's not a lie. Disclose your trans status before meeting, but try to get to know them better first and get a sense of how they might react. You won't always get it right, and some men may respond badly, and you'll have to block them immediately. This is how I eventually found my husband.
Another option is to use a queer dating app and specifically look for t4t relationships. There are a lot of cute trans guys out there.
