I would be inclined to make use of a lovely device known best as a shower shot. It's like a little mini shower dildo designed specifically for cleaning out back there before you start playing around back there. The only ones that I know of are available from Fort Troff. There are 3 main types that they seem to offer currently. They have the more advanced model, which runs into the shower plumbing with a diverter so that you can alternate the water flow between the shower head and the shower shot. That one is available HERE… It's the version that I have personally, and I swear by it, especially on days when I know that it's not going to be a whole lot of fun back there. The other two versions are quite similar to each other, yet different from the previously mentioned model. Simply put, you hang the bag over the end of the shower head and it's an instant shower shot. The more basic model of the two is available HERE, however I quite prefer their "ultra" version, formerly known as their piggy version, which you can find HERE.
This should help you to avoid such an undesired and ultimately, rather "shitty" situation (pun intended)….. Just a suggestion. 🙂
