It seems to me, that if your husband is telling you to enjoy tanning your pussy at the resort, and other people there do it, then it must be within the norm at the resort, and your husband must be approving doing it, and no doubt loving the beautiful tan that results. No doubt, he just enjoys staring at you as well. There is no reason for you to refrain from enjoying this yourself. Be proud of your body, don't hesitate to show it off. You obviously enjoy sunning and tanning at home. Good luck.
