I&#x27;m not sure why everyone is being so elusive with their answers. Nipples (on either sex) can become erect when exposed to cold. The band-aids are meant to imply that the women should apply them to their nipples to hide them from poking through their bra and shirt. If you&#x27;ve ever seen a marathon runner with two red streaks on their shirt running down from each nipple, you&#x27;ll better understand why. Some runners do, in fact, put band-aids (or duct tape, etc.) over their nipples to protect the tissue from rubbing against their shirt.
