Just signed up for this thread! I'm female, and have gotten the exact experience described by the OP all my life.
I have recently been interested in ASMR. I had never noticed it in myself, but started watching some videos after hearing an NPR piece about it. Finally got some of the head tingles for the first time the other day, from whispering audio after having fallen half-asleep. But it was pretty mild. Then today the pre-poop thing happened, which made me realize they are very similar! Which is what made me google it. Except the poo-phoria for me is full-body, mostly back and head, waves of tingles and intense good feelings. Sometimes overwhelming--if it is happening intensely I don't want to move. I am very goosebump-sensitive, but this is a different experience. It does not always happen, maybe once or twice a month. I also get a mild feeling of well-being and satisfaction afterwards, but that is different, that's more of a relief/clean feeling. I have never taken drugs so I can't compare.
I also get a non-tingly "high" from coffee. The feeling that the world is pretty awesome and positive and I want to talk to people. Since caffeine often stimulates bowel movements, the feelings sometimes combine.
Interestingly, I have two small children, and once one of them asked why pooping was so relaxing. The smaller one has recently potty-trained, and I notice him sometimes stop what he is doing, curl up and put his head down, kind of trance-like, and when I check with him, he admits he has to go. I suspect he is experiencing the same thing and trying to prolong the feeling, resulting in some rather horrific laundry.
