How judgmental are you about other people's sexual natures?

I’m sure that we all disapprove of people who use sex to hurt others. However, aside from that, in what ways (if any) do you find yourself judging others because of behavior that you think is sexual? Where would you place yourself in the spectrum of opinions about sexuality?

I see a spectrum that extends from the idea that anything goes so long as no one is hurt to the idea of some communities that we should abstain from all sexual activity entirely. You might see other end points to the spectrum of ideas about sexuality. Now, many people have a standard for themselves, but don’t object to other people having other standards for themselves. However, if you have a standard that you think should apply to everyone, what is it, and what rules would you include in that standard?

Some people believe that there should be age boundaries on sexual activity or implied sexuality. Others believe some behaviors are harmful, no matter what. Some believe there is no age too young to start discussing sexual issues. Some believe that two (or more) consenting adults should be allowed to do whatever they want in privacy.

I’m having a little trouble, I think, putting boundaries on what I’m asking about, but I’ll put this out there, and maybe try to refocus the discussion as we go along.
