If you have a big flaccid CK's are not for you. They are made for the average guys and not well endowed guys. My boyfriend and I both own the CK X Boxer-briefs and they are very constricting. We also own a few other boxer-briefs of theirs like the One and some others. I think you should look into boxers or a bigger boxer-brief and not trunks. Obviously makes a good one, but if you want to hid your bulge they won't be for you, and another is Banana Republic like someone mentioned. Not much of a bulge is visible in them. We wear boxers to bed as anything else is way to uncomfortable with night time erections.
