In an amusing thought, isn't standard steroids testosterone based? And don't they have a side-effect of feminizing a cismale body and mind because it then thinks it's producing too much hormones?
Either way, if the opposite gender hormones are too high with normal same-gender hormones, you can have some HRT-like development and supposedly even a little bit of cross-gender behavior. It'll also botch your reproductive ability to some end. I had this happen to a friend, as she had some masculine hair, felt tomboyish or something, and I think her build takes a little bit from a male too. ---HOWEVER, she still was quite female in her mind and body. I didn't even know that this was going on with her until we discussed my ->-bleeped-<-.
So if you have HRT-like developments, maybe, but I really wouldn't buy into it, especially if you don't really have developments that come from the other gender.
I think we put too much down just to pull out over potentially being hormone-imbalanced. It's like, you went through all this trial, went through all this experience and mindset...and now that you finally have come to the end of the journy---"nah, let's just go back the way we came. It'd be medically proper." It's like a slap in the face. But...that's just how I feel.
