I prefer the blunt answer as well, there really isn't much other or better way to explain it. Transitioning as a word itself is probably improper, in short we already transitioned mentally to what makes us feel alive. Now we just want our bodies to match our reality.
If the smile I have on my face when my hormones are in balance and I am feeling pretty is not telling I don't know what is lol.
I think the emphasis on before, rather than after is a mistake as our body has protections against this sort of thing. A true man would probably feel terrible on a female hormonal balance.
