It depends on what I’m wearing. For example, if I’m wearing athletic shorts, then I’ll typically pull the shorts and underwear down under the balls and pull both the cock and balls out. If I’m wearing a suit, dress shirt, and a belt, and especially if I’m wearing boxers instead of briefs that day, I’ll just unzip the fly of the slacks and pull the cock only out through the fly of the boxer shorts. In that Instance, it’s just easier than unbuckling, untucking the shirt, trying to make sure the slacks don’t slip down below the thighs and then tucking and buckling back up when finished. In short, balls out unless it’s going to take longer to do it that way.
