Hey Sailor. First off...that was far from gross. There are some posts on here that get real nasty...but that is all part of the disease so we live with it.
As far as your concern, I think it is normal. I am a guy also, and I have that problem every now and then. I have been to the dr (who actually was able to notice it) and he has found nothing wrong with me and didn't even go into depth on the subject. He is a really good doctor so I assume from his casual reference that it is a normal thing with CD. My suggestion would be to talk to your Gastro to calm your fears.
As far as how to handle it...grin and bear it. I tend to go to the bathroom more to just wipe. If yours is really bad, and I know this is going to sound bad, but have your thought about Adult Diapers. It won't get rid of the wet feeling but it will save your clothes.
Feel better and don't let it get to you. There are a lot of worse things you could get with this disease so I will take anal leakage of some of them anytime.
