I'm not a fan of the Klein grid it discounts the experience of people in the closet, or people who just haven't come to terms with their sexuality. For example, I'm gay. I'm at Kinsey 5, and if Ewan McGregor didn't exist, I'd be a solid 6. But if you asked me two years ago, I would have waffled uncomfortably around 1 or 2. But in the Klein grid, my uncomfortable past is worth the same as my confident present. Just because I had relationships with men before doesn't make me bisexual now.
