Well, not quite your story - but maybe something in common about how this can feel like...
I got some straight male (I guess... was married, now widowed) going quite dilly over my picture(s) in FB.
I don't look too male, though neither too female (IS IT JUST ME?!).
In your case, you came clear about your status - that too might have made me wonder ... in my case, I just have the same difficulty in figuring why some guy would go dilly over my pics. Are they for REAL? That's actually the thing.
If they for real, one sure would not want to be off-ish, or?
One thing IS for sure, that cis-females seem a couple of miles ahead of us, and then some, getting this stuff sorted way back during their first dating and more intimate affairs. Gosh!
I'm post-op but STILL ... am I freaking for just my own limited acceptance of myself here? This is where I seem to feel some empathy with what you say.
It's easy to talk, easy to surmise, but once IN a situation ... the jig is up, and then what to think, and what to do, is some sort of balancing act, isn't it?
Sorry to say, I'm as clueless as you seem right now.
Only wanted to say you not alone in this - even when we post-op!
