Should I take pictures of myself during sex and hang mirrors in the bedroom too?
Why do you want to take pictures of yourself during sex?
One can't be a really erotic person if one doesn't have a dozen of photos of them and their sexual life.
You are concerned about being erotic with sex, but to hang naked pictures of yourself where all can see is crazy. Be more thoughtful in case a child comes in the room, and worrying less about pictures. Those pictures can come back to make you regret the way you wanted to feel at this time.
I do not get what the big deal is if I want to put pictures up in my room. I should be able to do what I want. My kids should be fine with the images.
While parent's educating their children about sex can be appropriate, its wrong to expose them to such depravity. Their views on what a healthy sex life can be might be ruined.
