Being an inventive little sod i have sewn up a garment that holds all that is reqired in a nice tucked position .... It even alows me to go to the loo just like a girl. I wear one all the time ... even at night .... I have made a few so that I can change and wash them.
The last time I tried to put photos of my stuff here the mods took em off ... So i won't bother again!
Good luck .... just know that its possible!
