If you bind with big old bitties the likely you will have complications like Heavy breathing and broken ribs this shit is real being trans it not a mental illness but disphoria is considered one as in you shouldn’t have to feel disphoric hence why there’s medical procedures for it you still have to be safe about it
Genuinely do not listen to this rando. Tape CAN be a safe way to bind. I will say, if you’re using a traditional binder, make sure it is the proper size and not too small and NEVER use ace bandages or the like to bind. I am a 32JJ and my binders with baggy shirts only do so much unfortunately. At a certain point, there is no safe way to make yourself look completely flat (besides surgery), but there are safe ways to help.
