And you never know when you might need it. Sort of like taking a patch kit.
I used to do a lot of road biking back in the 1970s and 1980s. I never tried bib shorts, but was always tempted. At that time, the standard padded Lycra was about the only option widely available. My cock usually was to one side or the other, but on long rides, I had to move it around occasionally.
I don't ride much now, but when I do I usually use the two-layered type of shorts with an inner padded Lycra liner and outer baggy short, which is less aerodynamic, but less graphic, if you care about that.
I had one pair of Assos shorts which I got on sale years ago. It was absolutely my favorite pair till I wore it out.
