I have full coverage when flaccid. If I do not keep my glans clean it will develop an unpleasant odor. I have even experimented during the summer. By this I mean that I have showered, and been careful that my restored foreskin does not retract. This way there is not soap or water which rinses across the glans. After a couple of days doing this smegma will develop along with an unpleasant odor. I make sure that my glans and entire penis is cleaned thoroughly during my showers as I do not want any sign of unpleasant odor.
