I wear girdles to work routinely.
I keep a couple of corsets around for under evening gowns and certain party dresses, and sometimes even foreplay.
Anything tight below the waist or anything that interferes with the deep breathing needed for an enema will come off before I get into position!
I consider it part of the prep.
Girdles and corsets are one thing, enemas are another. I don't really consider them compatible in any way.
