All I can say is that on raising my E (and especially lowering my T), I felt as though I got to finally sit down in a seat I'd been holding myself up from all my life. It's like the difference between being a fountain, and being a lake. I just got taken off anti-androgens for 2 months, and I had to go back on them, I was getting pushed out of that seat, and there's nothing worse.
It's impossible for me to tell for sure what changes that have happened in my personality and habits and state of mind are 'caused' by the HRT. I've spent the last few months trying to learn to handle acute PTSD, which has somehow been brought to the surface by transitioning - but I have no idea whether my lizard brain is being kicked off by hormonal effects, or simply by me being myself for the first time since I got abused way back. I'm now strong enough to be vulnerable, safe enough to be unsafe. I'm taking risks I couldn't ever take when all my energy was tied up in "passing" as a man.
So much has changed since I began this change, and I don't care what's causing what. I'm just trying to ride the white water. My body knows it's a woman's body, I'm helping it to catch up with itself. My mind/self is female, but has never needed to be masculine or feminine. It's simple. Since I began transitioning, and especially since HRT, my sexual orientation has flickered about like a mad dragonfly, and worrying about that gets in the way of it being the mad fun it is just to watch. Trying to be anyone else's idea of what a trans woman "should" want/do/wear/be - that's just silly.
