Just kidding. Trans people are not obliged to disclose to anyone whether their genitals match their gender presentation upon dating, but it's considered courteous if things are getting serious. Actually no matter what you plan to disclose - be it a kink or body variation - its risky to spring a surprise on your first foray into the bedroom. Unless you met in an established LGBTQ setting, its reasonable for a new person to assume that you are cis. Everybody deserves the courtesy of a dignified out that doesn't involve bolting naked for the door. But more seriously, considering trans people are at a disproportionate risk of violence and murder, I strongly discourage my trans women friends from getting into bed with a cis man for the first time and playing Jack-in-the-Box.
Yes. Yes, individuals who are trans, and all humans really, have an obligation to be respectful, honest and forthright with their partners. Dating apps give users AMPLE options at disclosing such information. I see absolutely no justification for withholding this information because if you're trans and you're worried about violence you're probably past the point where you SHOULD have said something anyway.
Thank you, I am also tired of dealing with this but on the opposite realm. I attend a pagan ritual almost monthly where the senior druid always upon introduction by name has to add, "I IDENTIFY AS HE, HIM, THEY, THEM." Okay, we got it the first dozen times, yes, there might be a few new attendees, but let it alone, we accept you as you are, we're here aren't we?
Some of life's little surprises can kill you.
