Hello Davina. Greetings from across the pond. I really hope that you will be able to bring up the subject again with your wife and be able to get to some level of tolerance. It is something almost impossible for wives to understand, as the isn't something they may be able to do which could be compared. And let's face it, it is rather hard to understand even on the personal level... may take years to fully accept it ourselves.
Close your eyes, stay still. It doesn't matter if you are naked or wearing a tux or a frock. No difference... It is still you!
