Your relationship is starting to get serious and he or she reveals to you that...?

I was that guy, revealing that little tidbit to her early on before we got too serious. Yeah, she thought it was a bit weird and it wasn't her thing for herself, but we moved forward, got married, raised kids, and continue to love each other. It's just a rebellious streak. It's comfortable. I'm fine with what I look like naked and other people just look like people to me when they're naked. To me, being uncomfortable with my body or being offended by other people being themselves is nothing more than a sick cultural perversion I feel I need a break from when I can get away with it. Other people are fine blindly hiding themselves from each other in shame. That just isn't me. She still finds it amusing, but she enjoys my accepting her as she is, encouraging her to be nude as much as she wants.
