John, for the past 10 years, I've used a "Toto Washlet", which is a kind of bidet attachment for one's toilet. The jet is strong enough to provide me with help when some poop won't come all the way out.

At the risk of sounding a bit gross, it is possible to obtain the same effect with a shower wand in the shower (on the most "intense" setting). Gross it may sound, but it works.

I mention these things in case they may be of use to you and the community.
