Been 4 years in the German Air Force and I have one *extremely* hard time to imagine an FtM EVER being able to pull that one off!
Firstly Boot Camp, communal showers, sharing rooms with 5 other guys, all hopping around in pyjamas or less at times. That's already beyond my imagination, really.
Then moving on to the barracks, sharing room with 3 dudes and all that's going on there! Farting, cussing, etc. etc. some of it REALLY gross even for some cis-male.
Moving on as I did, to become NCO, and NCO school, extremely physical and of course swatting, more boot camp stuff, and finally back at the barracks sharing still a room with one other NCO.
Well, I have no bad imagination but this item just beats me.
Never mind binders, good man! Mixing vagina with penis territory?! Hey!
The guys would laugh at you if yours was on the small side, now how about sporting a vag?
Don't know what to say any further, it's almost too funny if not tragic.
Good luck though with the binder,
Axelle
