Do you want him to drink it? Cool:) If you are healthy he can start drinking from immedialtely but if you have some illness i think it's never safe. Sorry, I finished my points for you but very good question;)

E coli is a serious bug, be safe.

E-coli is not a single bug. It is a vast family of bacteria. Most strains are quite benign. There is a type that lives in symbiotic relationship in all human lower digestive tracts. It helps break down complex foods into waste and nutrients which our bodies can absorb. There are virulent e-coli strains too, but if your girl friend had one of these she would be obviously ill. Our stomachs can handle some benign e-coli. If you ever get really sick to your stomach, you vomit its contents out to rid the body of any potential poisons. Then the body opens the pyloric valve an sends up the contents of the top part of the small intestines. That purges any poisons that have made it past the stomach. The e-coli in this reflux do no harm. You probably wouldn't be safe putting pure excrement into the stomach. Since the stomach is not designed for it, that might be more e-coli than your system could tolerate. But a few rinses till the returns are mostly clear takes care of that concern. There are nastier things than e-coli in the intestinal track of those who are ill. Dysentery, Hepatitis C, and AIDS could be transmitted that way. So if you want to go for this edgy play, have a good checkup first and insist that your mate and you remain faithful to one another to avoid the risk of bring in someone else's infection.

You should have your bf give you a 3 quart enema with some Gold Dial soap added after breaking the bar down for 24 hrs. in just enough hot water to cover the bar. Pull the solid part of the bar out of the container,what's left is what you add to the 3 quarts of very cold water. Then rinse with 4 quarts of warm water,then 5 quarts of warm water held for 10 minutes. The next enema should be safe to drink.
