I've read most of this thread with interest.
IF my guffs could be controlled, I surely would, as I do find my lack of self control embarrassing.
Unfortunately, I have absolutely no choice, and it's not just with my partner, it can be in a crowded supermarket, the quietest of libraries, or literally anywhere.
Believe me, if I could prevent a guff, I would.
I am jealous of those who are saying they can delay for a minute or two to allow them to exit the room.
I can't delay for a second.
What I'm trying to say, is it's not a choice for everyone.
I'm certainly not intentionally being rude.
So after a lifetime of this, yes I can laugh with embarrassment, when it's in front of my partner, as he knows it's not a case of me being disrespectful, and like another pp partner, he really wouldn't make me feel bad for it, as that would be disrespectful.
Maybe give a little thought before judging anyone about anything.
