wow. this post and another that I just responded to sound like me exactly. I used to hold it as a kid and have had some episodes a few years ago when I first started becoming unable to digest lactose. I have had to hold it before because i was in the car or something. I wonder if there is a connection. I have a leaky anus sometimes too. yesterday for example, my butt was wet just about all day. I had to wipe several times because it was so uncomfortable. a few times I tried to have a bowel movement and only a small bit of mucus came out. I have the stale odor sometimes but other times it's just fecal.
