It could be due to the position of your vagina. The 'normal' position of the larger part of it is rotated 'forward.' However, in some people (due to a variety of causes) it can be lying slightly posteriorly. That, accompanied by the sex act (if you're on your back), presses rather strongly on the rectum and it can cause the muscles in that area to tighten.
There may be other reasons, but this is the one that comes to mind because of the structural relationships.
I should have included that I am male. :) It read on the internet from only 1 web site that men have this problem more so than women with sex causing dehydration of the colon. Any truth to this? Does any other men have this problem?
Straight sex. Not sex it self but the orgasm. It cramps up all the muscles in my abs or something. Like before a man pees the bladder is closed off before orgasm the same happens with my constipation. Like it is being compacted during sex, even if on an empty stomach, it just tightens up my colon muscles and can not poo for days. It really high up and enemas could not reach it. Might even be the small intestine. dunno. Just looking for possible answers.
