Sex positivity is the idea that all sex, provided it's healthy and explicitly consensual, is good. But what happens when a complicated theoretical idea like sex positivity gets packaged up for the mainstream? And which voices are missing from the conversation?

Sex positivity is the idea that all sex, provided it's healthy and explicitly consensual, is positive.

Philadelphia-based sex educator Melissa Fabello describes it like this:

"It ended up happening and it made me feel terrible... Something I've noticed, especially with my female friends, it that the culture of sex positivity encourages them to go out and be promiscuous and experiment with their sexuality which is a cool thing... encourages bad and undesirable experiences for the sake of experiences," she says.

Melissa Fabello says the idea that women want to be sexually liberated has been turned into an expectation that they have to be "up for anything."…
