For a variety of already describes by me, medical reasons, I am against stuffing the testes into inguinal canal. I have a rather small penis, and I solve the problem by wearing the elastic belly control underwear, and tuck everything into place, once the panties are on. The spandex feature of those panties is strong enough, to keep everything tucked away without any problem, and I can wear any kind of very tight fitting leggings without showing any bump. the crotch area of these panties is wide enough not to allow any of my parts to slip out to the sides. Everything is held nicely in place.
I can go to the bath room in the normal way, and have nothing to un-tape or re-tape.
