Hanging and defecation reflex

[Mammoth Member Find all posts View Profile Close Mammoth]

I'm encountering a weird problem : After hanging S.D. for a set or two I get a really annoying feeling of wanting to poop. Even if I pooped earlier I'd still have it
I'm guessing the tension on the penis is causing some muscles/sphincter to contract and giving me this urge to release...

Has anyone faced this and what would be the solution ? It's really starting to deter me from hanging

Well I tried asking Bib about it, he said he's never heard of this before.
