I don't get how you jump to accepting testosterone procedure as a means to becoming more boyish. Like what will it do for you? Make your butt weird hairy? You know it plays a different role in female bodies than male bodies, right? You're injecting horny chems with side effects, you are not getting what dudes get from it.
As a guy I don't think of testosterone as a thing I need to maximize to be me. I typically think of it as a chemical that helps motivate me to pursue success, but even that might be inaccurate because apparently cortisol has more correlation among businessmen. Even so, it isn't like testosterone is applied over the entire lifetime of a man. Hugging your kids decreases testosterone, indicating that t has a role in the early-middle parts of the life cycle. Hormones are signal chemicals, not stat points for an RPG character.
