Transgender Support Group
This community is here to support and help the large population of transgender people. If you or anyone you know identify as transgender, this is the place to share your feelings and experiences and speak with others who are going through similar things in their lives.
I don't know you or your wife's sexual preference so I'm not sure if you are still attracted to her or not so this might not even be relevant, but I can tell you what would have helped me when I was feeling like this. Make her feel beautiful. Make her feel desired. Don't try and one-up her when it comes to clothing, make-up etc. And definitely don't make any comments or give any criticism (constructive or otherwise) to her appearance or her own femininity. She needs to be remind that she is still a beautiful woman even though she is now sharing the womanly role in the marriage with you.
