At first I only bound for passing purposes, when I left the house. Then I started to leave the binder on even after I had come home. Within a month or two, I was binding all day, even when I didn't leave the house, because of how it made me feel. I hated taking off the binder at night, but I did it.
I had a very comfortable binder. Maybe that helped me to feel less dysphoria even when I wore it in private. I don't know.
I have had a similar experience with packing. At first I wore it only to my men's group, just in case anyone was checking out my crotch. I was surprised to find that it made me feel more natural. Now I pack all day and all night. The only time I don't is when I shower.
Now I'm living alone, and I still pack 24/7. Funny, I thought I might not. But it's all about how it makes me feel.
