I ready an arrival long before I got married about how one couple showered together every morning. Keep in mind they are in there 60's now.  They told the world they do this to allow each other be comfy in there own skin around their SO. No matter how much their body's changed they never had to feel uncomfortable. My husband and I have been together for about 2.5 years and eveynight we sleep nude so no matter how my body changes for good or bad I don't feel sexy in his eyes.
