LOL - kind of ironic that the first two replies to your post are from FEMALES....but anyway......
Yes, from what I have read (and heard from other males with IBD) these issues can occur, and can resolve when the inflammation in the bowel slows down - like Dusty says, the inflammed bowel puts pressure on places it shouldn't so not only squeezes things it shouldn't, but because it is inflammed it can cause surrounding argans to pick up on that inflammation and become "ill" as well.....
Women don't have a prostate, but we do run into similar issues with our "lady bits" too....lol.
I hope it does resolve for you soon, and is not causing tooo much pain.
