My experience with the gender talks only came about when it was necessary to talk about it. Earliest times were when I was about to begin hormones (age 13). It was discussed with my family, drs, nurses and close friend who was also mTf but 5 years older. When I began living on my own (age 17), it was only discussed with husband #1 (really should not have married, but foolishness). Then again with husband #2. Between #1 and #2, I lived with my best friend (cis female). It was never discussed except on one occasion when the group of us visited a gay bar to watch a drag show and we all commented on the nice looking performers and what a fun life that must be. I think that was about it. No one, that I know of, knew the nature of vaginal shortcomings. We talked about sex in general, sex with other girls -- no way -- and guys and clothes but I've yet to know many women who discuss the nature of their vagina with one another. We talk about our periods, moods, etc but never about the vagina or lack thereof -- lol -- although I've been tempted on many occasions to just exclaim I was born without one. It was necessary to mention the trans stuff with a couple of gentlemen before husband #3 (the love of my life!!).
I guess I never had any real issues to want to discuss the nature of what is between my legs with someone unless it was a sexual or medical reason. I can understand how others would want to do so because they have literally gone through a "trans" ition from living male and then having to do away with all the male stuff to become who they truly are. I only feel the frustration of being born without a vagina, but sometimes I read about others whose lives have to completely change at a high price. I can only imagine their discussions and in my mind I am holding their hand tight to give them comfort.
