Gender, phys, HRT.
Estrogen has had some unusual side effects.
For one thing is's an Unfair performance enhancer in the machine shop.
For another, I'm gaining Muscle Mass like never before in my life. I feel Bionic when I'm not Exhausted.
This has resulted in a Strange Gender Nexus. Estrogen does all that and a bag of chips like Usual, but also gives me major bonuses to my favorite 'Male' attributes. So much so that it's swung the needle back towards Masculinity overall.
If I'd known all this out ahead of time I'd have started HRT first thing. I went to my ass to get to my elbow, genderwise, and ended up damn close to where I started.
