My post on supporting consenting adults doing whatever they want sexually articulates one facet of what’s known as a sex-positive outlook. And yet there are actually a number of ways to interpret what it means to be sex-positive; some people think of it as “yay, orgasms solve everything!” while others use it to mean having a non-judgmental attitude toward sex.
For that reason, I’m a big fan of Pervocracy’s What I Mean When I Say I’m Sex-Positive post. The post presents a clear and comprehensive explanation of what the author means when the term sex-positive is used. I highly recommend that you read it, and consider which, if any, of those ideas apply to your own outlook about sex.
