The scale you guys are talking about is the Kinsey scale. Kinsey didn't theorize that all people were bisexual to a degree, but rather that many bisexual people were on a scale; some leaning more towards homosexuality and others leaning towards hetero sexuality.
Kinsey was also the guy who brought about the 1 in 10 people are gay theory; but was thought to have been incorrect because his test subjects were largely prisoners. This was one of many of his findings that were questioned; including the large number of people who masturbate (90% male and 40-70% female). Actually studies have found that Kinsey was fairly close to the mark; for people who masturbate, he actually low-balled it. The numbers other studies come up with today are much higher than Kinsey's; of course society could have changed, it used to be believed that tugging the general led to depleted sexual energies which caused impotence.
Alfred Kinsey, an interesting figure. There's a good movie about his life starring Liam Neeson.
I describe myself as a little dose of toxic masculinity.
