I recently got chewed out on an atheist blog for a comment where I suggested that "slutty" behavior isn't healthy, normal, and praiseworthy. Any thoughts? Should I be more sexually enlightened?
No, you shouldn't. You should establish your own boundaries as you feel comfortable and not let others coerce you otherwise. It might also not be such a bad idea to be cautious when speaking criticisms about other people's sexual preferences, however. Each to their own.
