I was sort of thinking about the question in the same manner. I was also thinking maybe she needs to go down to the local United States military hospital and take a poll among the infantry guys who have suffered grievous groin injuries. Actually, my Vietnam company commander took a mortar round between his legs. I wonder how that turned out for he and his wife. I think there is some serious fantasy occurring here. "Yikes, my nuts are shot off. Now I can reconstructive surgery and become a woman!"
My wife's cousin has a child who is transitioning from female to male. I think the "what if" question does a disservice to those men and women who are transsexual and not just plain old vanilla cross dressers like me.
