I have plenty of naked pictures of myself and my ex's. I will never, ever ... in my life, show them to anyone if ...
1) that partner is not present and
2) did not give consent.
3) if it was to someone that could not appreciate and respect that lifestyle.
And if I ever found that one of my ex's had shown, that would be the end of that person, and any thoughts of them ever going naked or being accepted back into the circle again. I am quite sever in that way.
