Of course not, but giggle about it, and being "macho" about it is a little daft no? Actively trying to squeeze one out or purposefully doing it to me seems childish.
Sure, it happens! I'm not saying it shouldn't ever happen - however, it's not really pleasant, and I think the point being made is that purposefully squeezing out out is just gross. If you have that much control over your bowels then go out of the room.
It happens in our sleep of course and you can't control that, but it's just the active purposeful childish "pull my finger" sort of behaviour that I find gross.
