It definitely can be uncomfortable. There’s a reason advice about binding safely exists. But while my binder is less comfortable than my really comfortable bras, I wouldn’t say it’s really less comfortable than, say, my high-impact sports bras or some of my underwire bras. One thing I like better about binders is that the straps can be more comfortable for me and it’s nice not having so much of the pressure isolated to a single band (I’ve always had trouble getting band sizes that fit me).
Response to How Normal Are You Really?:
I’m 28 and have never had an opportunity to try pot. I’m not theoretically opposed to it, but it’s illegal where I live and aside from being a little paranoid over getting arrested, I just haven’t had any friends who openly smoked it around me/offered me any, and I’m not going to go out my way to find some.
