To clarify my current situation:
I'm heterosexual and no current partner. Vegetarian, if that matters.
And Switchablesusie, are you psychic? I must admit, pleasure is my main motivation and the health benefits are a bonus.
I'm trying to listen to what my body wants. I did a series of 3 enemas Saturday averaging 1.5 quarts each, with about 1 tsp salt per quart.
Sunday I did a series of 3 twice, one in the morning and one late afternoon. Both prepared the same as before. I doubt I held any of them longer than 5-10 minutes.
I enjoyed the sensation of 1.5 quarts immensely and could feel my bowel contracting. Around 2 quarts I'm feeling very full, almost uncomfortably so. Nothing of what I'd consider painful but I decided better safe than sorry and didn't try to go for 3 quarts.
All day today I've been monitoring my condition to see if I have any symptoms of overdoing it. No headaches, no dizziness and I actually felt pretty good all day with plenty of energy.
As delightful as it sounds, I don't think I'm a daily enema kinda guy. I'm concerned about my intestinal flora and I'm paranoid about disrupting it too much, especially if I decide to do this several times a week.
Thanks again for the replies.
