While this from an advice column from The Guardian, the topic is absolutely relevant within the realm of healthy lifestyle. Pamela Stephenson Connolly makes an interesting point—this is not a health issue; this is about unhealthy concepts of what a couple's sex life should be.

Stephenson suggests that it's the increased availability of pornography that has remade the idea of 'normal' sexual pleasure, which is a similar argument made regarding fashion and beauty magazines and body image. What do you think? Do we have unrealistic, unhealthy expectations for sex? Is the porn industry to blame?
