It is surprisingly sane. With the one caveat that OP claims to have literally changed sex through medical transition and to be a literal woman, which means they are still trying to uphold some unhealthy cognitive dissonance.

It would be one thing to state that medical transition is about trying to physically resemble the opposite sex as much as possible, while recognizing that they can never actually become or be indistinguishable from the opposite sex under all circumstances even if they pass under some limited circumstances. And that medical transition still does not put you in the dating pool of people looking to date your target sex. It will understandably take you out of the dating pool of those wanting to date your natal sex but rather than going to the opposite side, you just end up in the tiny dating pool of people who are specifically attracted to feminized males/androgenized females/people with mixed sex characteristics. And that category inherently includes a lot of fetishists and people looking to experiment because you have physically transformed yourself into something that does not exist in nature.

It’s just not healthy to have this idea that anyone who dates you won’t be presented with constant indicators that dating you is not an interchangeable experience socially, functionally, and sensorily to dating your target sex. Of course, extenuating factors may contribute to a partner wanting to believe you are a member of your target sex. For example, a male-attracted woman with male-related trauma wanting a way to date a man without dating a man. A male-attracted man with internalized homophobia fearing social consequences for dating a member of the same sex. The list of possibilities is endless. But mutual cognitive dissonance is not healthy and does not make for a stable, loving relationship. It’s a ticking time bomb.
