Hello,
I really like them. I have several posted in my gallery. But, they do tend to be tighter in the thighs, which helps to keep them on. The Levi's Offenders are very low, and comfortable. I wear them all the time. Unlike some that are really cut for ladies these are for guys, so they fit a lot better. The fly is only like 3 inches long with one button, and yes you do have to watch out that your erection doesn't find its way above the waistband, especially if your above average.
And, yes I think my cock shows more, which is cool with me for the most part. I do like the feeling of my low rise on my hips, and they are not falling off either. The downside of the Offenders is that they are expensive, often $100 unless they are on sale or at a discount place.
