Well that argument applies in all manner of circumstances to any part of anyone's anatomy, but it's certainly no grounds to pressure a cyclist into wearing an alternative to normal cycling shorts. I find it incredibly easy not to look at people's crotches, unless I wish to. Why do all these other people find it so difficult rather than be sensible and adult about it? Of course he can feel uncomfortable with the unwanted attention, and to seek advice on measures to reduce the unwarranted focus on the area in question if that is his preference. I haven't said anything that suggests otherwise. He's the one with grounds to feel aggrieved here after all - not the crotch-fixators. Everything I've said has been directed at people who think they are somehow entitled to focus and comment on it, and pressure a cyclist to change their clothing, when all he's doing is minding his own business as he traverses his workplace.
