Let me rephrase, and then I'm going to back out of this thread. I tire of the nitpicking, sorry.
If I was being denied sex for the duration of a relationship, because it was being saved for marriage, and I was not told that the genitals being withheld were the expected ones for the presented gender, only to find out after marriage that they were not a) the expected ones, b) the ones I prefer and c) incapable of being used the way I wanted... Well, yes, I would most likely be extremely pissed, and would likely want out. Mostly because of the lie, not because of the genitals. This should have definitely been discussed before entering into a marriage contract.
And yes, I'm postop MTF, so I have a very personal interest in these situations. I hate that I have to disclose, but that's life. But with me, the only issue will be that of acceptance, as I'm very capable of performing as expected.
