Yes it could. Seeing your lover.s nostrils flare and her inhaling deeply the gas expelled by your now protruding anus muscle. That is intimate and loving. Especially when you get up and look in her eyes and notice she has a small brown stain on the end of her nose and her nostrils are still flaring searching for the location of the next volley of gas.
