I want to know the answer to the following question:
Who invented the KSOG?
All the background I'm provided with is that "Introduced in Klein's book The Bisexual Option, the KSOG uses a 7-point scale to assess seven different dimensions of sexuality at three different points in an individual's life: past (from early adolescence up to one year ago), present (within the last 12 months), and ideal (what would you choose if it were completely your choice).". Is that enough to answer the question?
Answer: no
