I think your gonna have quite an issue trying to control those bowel noises. Sure making sure your eating stuff that is not as hard to digest or produce less gas is the way to go but I've had bowel sounds when I had a healthy colon years ago. I think unfortunately you are stuck and a lot of people would think eating earlier will help with that issue also but I've found from experience that my stomach start making more noises around bedtime because my stomach is looking for food to digest and I also get hunger pains. Is this causing a problem in your relationship? Does he know exactly how your digestive system is set up to work because maybe this is something you want to explain so he can better undrrstand. If that is an issue for this dude maybe you should start looking for a replacement. Just a suggestion. Good Luck.
