When would you prefer a trans guy disclose his status to you?

Regardless of whether or not you find trans men attractive, when do you think is the best time to be personally disclosed to?

If it’s in person is it acceptable after a few dates? Or upon first showing interest?

If online, is it acceptable to only bring it up once discussions about intimacy arise, or should it be listed on the profile first thing?

If you had to wait longer, would you feel led on or deceived? Or would you not feel very strongly even if it was a dealbreaker?

I try to disclose immediately since I know it’s a frequent dealbreaker, but I’m also concerned with safety, so I’m interested in hearing what seems to be the best way of approach.
