I know that commenting on people's appearance is rude and often unkind, so I'm making a general point here, not pointing at anyone in particular.
So much of our sexual attraction to other people is based on physicality. Starting with sexual orientation, but beyond that we all have preferences for appearance. It's not the only thing of course, but it tends to be where we start.
We might be more attracted to tall men or blonde women or people with long hair or bohemians or men in suits or whatever. I suppose everyone has been surprised by a sexual spark with someone who isn't their usual type, but physical attraction is an important component of most relationships.
If you are a 50 year old, six foot male who decides to express yourself as a version of womanhood, chances are your physical appearance is not going to match your inner perception of yourself.
Your pool of potential partners immediately shrinks because, while the dating pool for middle-aged men is probably quite large, the dating pool of women-attracted women who are willing to accept male genitalia and are attracted to someone who's outward appearance is unusual is much, much, much smaller.
The decision to transition will limit potential partners, that's reality. No-one owes anyone sex. As humans we owe other humans respect, compassion and kindness, but not physical or emotional intimacy.
It's deeply offensive, that having made a serious life decision, they are unwilling to live with the consequences and make such efforts to shame women into making their bodies available.
You can't force someone to fancy you; not through blaming, shaming or aggression.
