Thx for reply, with so many upvotes already, super valuable info from many!

Wearing big signs. Super bad for sake of both haters and chasers. lol nupe. I think we all agree here.

Genitals are often quite important in most sex activities, and imHo there is nothing bad with liking cute dicks and vaginas. It is about physical parts in crotch, not about gender I feel, identify, express self as. Even more, it has nothing to person being respectful or not to the partner.

For gendered spaces like toilets, do we even talk about them, or relations between two adults, that both wants to be con?

I believe we are of what we feel like, what our minds are thinking, how our bodies do look, something something genes, how we presence self, how other see us. If someone wants to be an asshole and build relations or even marriage with kids based on how the partner look, totally ignoring the character of other person. Like, for own social status only, what's then? Do You want to force them into liking my personality too? (Sure, humanity expect us all to note my personality too, but some just wants to be assholes and ignore some parts of me). What about family being very important to someone, with own kids, "made" in traditional way with partner, in the primal natural way. Then vasectomy is also a problem, lacking breast of mother may be too. Do You want to force these soon-to-be-parents to surrogacy or adoption? Or maybe respect their way of life?

All Your mentioned what-ifs may be problematic to some, even big no-no barrier. In very same way as dating trans persons. That's why I've asked to talk first before acting. No, not by signs, or arm band (lol).

Call me old, but that's why we used to have "no sex until 3rd date" rule, to get know other person at least a little.
