I enjoy feeling the urge and looking forward to the enena adding to the feeling.
Me too but with the pre-enema suppository optional. In 50 years of enemas I've almost never needed or wanted a suppository for anything. My one experiment was a few glycerin supp's just to see their effect, but essentially nothing happened, and me with a super sensitive LGI tract. But when I pumped in my one and only 10% glycerin enema, OMG did that work, and fast. I only use about 5-8% glycerin now. (Yes, yes, I know, wimpy-ass colon. It is what it is.)
I am however very interested in what people either do or in my case are consensually "forced" to do while holding large enemas for long retentions, since my favorite enemas are with my wife or GF being Domme and giving me multiple-hour enemas and enjoying me struggling through it as her sub. After filling and plugging me with a DBC, she often wants to see me get up from the bath rug and show both of us my belly distention in the mirror. This is followed by various chores and tasks around the house including orgasms for her while she admires her handiwork. If she's in a good mood eventually I'll be permitted an orgasm and enema release.
