A significant aspect of my enema/douche equipment fetish, is having experience with every type of equipment available. While the ultimate bowel outcome is pretty similar regardless of the delivery system, the other outcum is often influenced by those different styles and colors. Another aspect is relative to the administrator of any particular enema.
Certain delivery systems only provide a fairly minimal amount of solution, hence the expulsion is influenced. The solution can be a factor, even in small quantities, and dependent on the desired outcome. Soap, glycerin, lemon juice, M&M, etc. can turn a smaller volume into an explosive release.
Much of my fetish relates to the vintage equipment options. I really enjoy those items which help replicate certain situations of my 68 years of experiences. Items made by US Rubber, Rexall, Goodyear, BF Goodrich, Faultless, Miller, Acushnet, Davol, Sears, and so on, each have their unique shape, color options, marketing names, and styles.
I have my favorites depending on circumstances and the ultimate outcum keeps me hooked. While I enjoy some of the newer large volume equipment with oversized bumpy nozzles, the very old vintage gear still helps trip my trigger and is a reminder of times long past. Some of the embossed designs are surely quite intricate and likely influenced our mom's and grandma's selection from the local drug store.
I still thoroughly enjoy the “Defender” series, but “Victoria” is always hanging around to fulfill those more desperate needs. The “Olympic” series is certainly deserving of a gold medal and my US Rubber “Royal” series treats me as a king or to a Royal Flush as it were. I don't rely on these very often inasmuch as I try to ensure they're always in primo condition for their age. And let's not forget those various folding travel syringes which evoke a psychological reaction of their own. Oh what a dilenema (dilemma), when trying to select today's system!
