As I read this I began with humming and hawing and wondering about the legalities, moralities and ethicalities.
This was so well-written with exquisite detail and openness that by the end I felt that I comprehended each each (necessary to know) aspect. I think it it a very good idea for three reasons:
First, it would make both of you very happy.
Second, you would not be keeping secrets from your families and friends.
Third, it is a step for us all recognizing that people can enter relationships as a man and woman regardless of their sex. One little step at at a time and this is yet another one.
This should be a big affair when lots of people and partying. NOT A GOOD TIME. I would hesitate to suggest delaying the happy even but consider, perhaps a year to make preparations, maybe a sort of bridal shower (or party anyway), that sort of stuff.
Oh, and my very best wishes for your happiness and extend my congratulations to the lucky fellow.
