Posting this because there might be an interesting discussion around the topic rather than because I necessarily agree with the article.
These kinds of articles always make me feel like the authors think that being sex positive means forcing yourself to have as much sex as possible. They also always point out that nobody feels comfortable about the amount of sex they're having. It's always too little or too much. And people apparently are constantly bragging about how many people they're banging? I can think of one friend I've had that did that, and that's it.
Speaking as a European, I can't help but think that this is connected to the deep American malaise surrounding sex. Obviously I'm mostly seeing you guys through your media, so perhaps I have an unrealistic view of how things really are over there, but personally I've never felt much shame about my sexuality, and I haven't felt like my friends do either. Not that we discuss sex that much, I guess. I'm not saying I've never had any issues, or always felt like I was having the right amount of sex, but it seems so overblown in the US.
I'm somewhat perplexed by how sex is portrayed and discussed over there. The media seems so hyper-sexualised, in a very artificial way, and yet there are still large parts of the country that have abstinence-only sex. ed...? It's frankly bizarre, and I'm not surprised that people end up having uncomfortable relationships with their sexuality.
