Hi Cynthia,
As you know, I'm still with my wife. She still goes up and down, one year after going full time. Expect that.
Overall, I think you are making progress in your relationship. Your wife, in some ways, is in transition as well and it's one she really doesn't want to do. Be patient and understanding. There is hope.
As far as the orchi, I had one and I still get erections. It takes time, it takes desire. But it still works. It's more a matter of brain vs. equipment. Most will not get erections because of the dysphoria and it doesn't mentally fee right to them. There is nothing wrong with that.
Hang in there!!
Hugs,
Jen
