I've contacted Dr. Marci Bower's office. In response to my question about permanent weight lifting restrictions after hysterectomy, they said that surgery always comes with risks, but they have never had a patient have this problem, and that a 6 week to 3 month recovery period and gradually building back up after that should be fine.
Further, Dr. Bowers can do the hysterectomy, vaginectomy, and metoidioplasty in one procedure.
Everything else I've heard back from the office is encouraging.
Emailed back asking for confirmation that my understanding of vaginectomy is accurate, e.g. that no cavity remains, as well, plan to update again when I hear back on that, as that's of interest to many of us here.
I'd initially planned to go to Dr. Stasevich in Belarus, but he cannot combine the three surgeries into one sitting, and air fare from here to Belarus is shockingly high, which nixes the financial advantage in my case (especially if I needed revisions). And I'm not sure I could persuade myself to go through the looky-loo-touchy-feely airport screening procedures prior to surgery. After surgery I fully expect to be able to do air travel, I can't see caring much if a screener finds out I have a tiny dangle, but anyone other than a medical professional looking at or touching what's down there now seems approximately as unappealing and insurmountable as eating an entire fresh elephant bowel movement.
