When taking an enema solo I enjoy the tube slowly inserted into my rectum. Also like to hold an enema while strong cramps. The best part is the relief while emptying the bowels.
The part of the enema that I enjoy while someone is giving me an enema is the excitement when the giver lifts my cheek exposing my anus and the slow insertion of the tube especially a colon tube. The embarrassment while the giver is looking at my most secrete area while inserting the tube.
That is what my feelings are concerning enemas.
