Glycerin bar soap and glycerin plug

I saw a post but cannot locate it about using glycerin with an enema for a hard hold. What about using a bar of glycerin soap? Do I use it like Ivory or Castile bars? How much bar per water solution?

I also saw a post but cannot locate about someone who made a plug with glycerine soap. Any tips on this as well. Thanks

A small amount of pure glycerine will cause a very strong urge to expel; more so than a glycerine suppository in my experience. A glycerine-water mixture or glycerine added to an SSE will similarly result in stronger cramps and urges to evacuate. I'd advise starting slow. A 5-6% solution (approx. 4oz in a 2qt SSE) will cause me to have a near continuous expulsion until my entire colon is empty (and discomfort after). Some have posted using up to a 50% mixture. I can't image that would an enjoyable experience.
