This question comes from the exchange between Ham and Flying Narwhal on this thread:  https://atheistforums.org/thread-53967.html (relevant part begins on page 2). 

So, I got curious and wanted to ask here. If you were initially attracted to someone you saw and spoke with (maybe went on a couple dates with), and found out after the fact that this person is biologically male because they told you, would this fact alone be a deal breaker to you in terms of continuing to pursue a romantic relationship? Would you no longer feel sexually attracted to the person nor interested in pursuing a romantic relationship with them? Please be honest and explain your response. 

*Assume this person has done all the sex reassignment surgical procedures/hormone therapy, etc, for the transition process and looks feminine.

That would be a bridge too far for me.  But you did remind me of this joke.

Quote:After a long night of making love, the guy notices a photo of another man, on the woman’s nightstand by the bed. He begins to worry. "Is this your husband?" he nervously asks.
"No, silly," she replies, snuggling up to him.
"Your boyfriend, then?" he continues.
"No, not at all," she says, nibbling away at his ear.
"Is it your dad or your brother?" he inquires, hoping to be reassured.
"No, no, no! You are so hot when you’re jealous!" she answers.
"Well, who in the hell is he, then?" he demands.
She whispers in his ear: "That’s me before the surgery."

Love is love. If you really, sincerely cared about that person, I don’t see why that would matter.

It's easy to imagine what one might do in a hypothetical, romantic situation but if you're actually in it and living it, oftentimes that all goes out the window.

If I'm looking for a romantic partner, I expect a pussy between those legs. It doesn't matter if they were originally born with one or not, but I would like there to be one when I'm ready to get intimate.

I wouldn't be sure until it happened and at my age I'm very sure it ain't gonna happen.

It would not be a deal breaker for me in the slightest. I wouldn't even blink. Perhaps I'd worry how some family or friends would judge me but then I'd think "fuck them they're bigoted idiots if they judge me."

If I'm attracted to someone's mind and body, then I'm attracted to their mind and body. Discovering after the fact that their chromosomes are different to I initially thought is about as relevant as discovering that the Slovak word for "apple" is "jablko".

I don't even think a trans person should have to tell the other person that they're trans. Why would it or should it matter?

Now I would certainly be against anyone to lie about it and say they're not trans if they are... but that's just because I'm against lying in general. I am not against irrelevant secrets that are nobody else's business.

If I were trans myself and I didn't want to tell anybody... I wouldn't.

I can really see it mattering .Really the only deal breaker is if they demanded exclusivity. I'm poly here now and forever .

I didn't know how to vote based on your wording (my problem more than yours, I'm sure). But I don't care if said woman started out as a man, as long as all of the woman parts are there and none of the man parts are there.

The anatomical features would not bother me. If the person has an unhealthy preoccupation with the drama of the sex change it would bother me. I am not comfortable with pretense.
