I have definitely participated in hook-up culture, and some of what was said rang true, although my experience was a bit different. Most of the people who were interviewed were college freshmen. I would say that my experience as a college freshmen was similar to these girls: defining feminism as both sexes being able to equally "use" each other. At the end of my Junior year (two years ago), I was introduced to the process of deliberate consent. I consider the three main tenants of consent to be (1) holding myself responsible for voicing my wants and needs (2) creating a safe space where my partner feels comfortable voicing their wants and needs and (3) being attuned to my partner's body language. Sex became not a struggle for power but a space for mutual support and healing. The ideas of sex in our culture are so messed up, if people see even consensual sex as a game of power, no wonder one in four women and one in six men will be sexually assaulted in their lifetimes. I feel like I have had the best of both worlds for the past few years. I was in a year-long polyamorous relationship, maintaining a deep connection with my partner while forming connections with others, some of which led to lasting friendships. I think it is important to be able to take sexuality out of the context of a relationship, which is what these girls are doing. I think so many people put relationships in a different category than friendship. I mentor a group of teenage girls, and they told me yesterday that they don't think its important for people in a relationship to have anything in common. Its the "feeling" that matters. That "feeling" is going to last for about two years, and you are going to be stuck raising a family with someone you have nothing in common with. In my experience, the people who abstained from sex got married way younger, and the first of them are already starting to get divorced. Sex is definitely important in a relationship, but at the end of the day its a primal, bodily urge. It should not be confused with the mentally challenging and exhausting task of forming a lasting partnership. In an ideal world, I would raise children (if I choose to have children) with my best friend, or in a community, and have lovers on the side. That seems much more practical than basing your life partner around sexual attraction. As far as these girl's isolation, their lack of "discernment, empathy, and patience," I think this is a symptom of our society at large, not just of sex "without attachment." I think it is great that these girls seem to have developed better self-confidence (although the feminist's wistful sighing at the end suggests otherwise.) It is so important that women learn to express their sexuality on their own terms. If they choose to abstain from sex until they find "the one," awesome. If they choose to have a ton of partners, good for them. They should be supported in their decision, and given the tools they need to make smart choices.
