What are some obvious and not so obvious things that help put you in a sissy headspace?
For not-so-obvious: posture training! This has helped me out immensely lately. You can do it basically anywhere and it leaves no evidence behind ;)
Examples include sitting up straight with an arched back, various submissive postures, and of course sitting to pee.
Admiring the feminine parts of your body in the shower or in the mirror can also help a lot.
You're so right about posture! I like working on my walk. I also find that heightened awareness of the small of my lower back, which I get when I'm walking effeminately, makes me feel more feminine, and creates this positive feedback loop 🥰 I'm going to try more static postures like you suggested, which should be fun! Admiration of feminine body parts is another good one. You're a treasure trove, Sophia 😁
