Do we not owe disclosure of certain things as part of our social contract? I would expect a partner to disclose certain things that are non-obvious, but potentially relevant to a relationship/hookup. But maybe I’m wrong, or painfully backwards. I would like to know, though, if you believe we owe no disclosure at all, prior to an engagement?

If you are not into trans women, the onus is on you to disclose that, not on the trans woman. This is because there is a long history of violence against trans women who disclose it, so as a cis man you need to do your part.

I think you might be right! I never thought of it like that.

If someone starts a conversation with you and then asks you on a date, you have no obligation to tell them anything.

However if a person driving a Ferrari wearing a 5k suit and a 50k watch asks someone on a date, that person may be under the impression that they are going on a date with a rich person and that they will not be going to McDonald's.

I'm not saying that there is anything wrong with taking your date to McDonald's. Plenty of people love McDonald's. But it is not the same thing and that date may not go well.
