Sorry, I think you misinterpreted what I was saying regarding prior history being irrelevant. By "irrelevant," I meant that I feel that one's gender assigned at birth would ideally not be what precludes a potential relationship, but the feelings that you are expressing regarding genitalia specifically. I.e., what I am saying is that it would be preferable to hear "I don't like penis" than "I don't like that you are a man." Is that so bad?

Just because you identify yourself as a woman doesn't mean that I have to see you exactly the same way.

That's fine.

the idea makes me uncomfortable

I can see that this is clearly the case.

Your right to your own identity does not supersede my right to my own sexuality in the context of intimacy with me.

I do not desire to get in the way of your choice of sexuality in any way. I am not sure how you extrapolated this idea from what I wrote.

Your safe space does not extend to my genitalia. I don't owe you that.

This isn't about the genitalia of people who have sex with transgender people, this is about the genitalia of the transgender people themselves. I don't see how the idea of seeing another person's penis should cause so much emotional trauma. (I.e., in the worst case scenario, a trans woman does not reveal that they are pre-op prior to intimacy, and their potential partner affirms that they are not interested in sex. In said scenario, the worst that I can see happening is the potential partner has seen a penis. This does not need to be the end of the world, even if it is not an ideal scenario, let alone some form of assault as many here would seem to suggest.)

Also, specifically, when you write

I don't owe you that

and

You have no right to that.

and

That barrier is mine alone.

you seem to be saying that trans people feel entitled to sex / intimacy with cis people. I can't speak for others, but I certainly do not. All of your response would seem to imply that, again, the goal of trans people is specifically to deceive and invade spaces, when trans people are just people who want to live as normal lives as they can. A trans person wanting to be intimate with consent is not a rapist as you seem to be implying.
