I think you are describing instead the worldview (or lack of one) of a bisexual man, who will screw just about anything in sight.
Most homosexual men are traduced and seduced young, by older homosexual men (the 25% or so who voraciously and viciously pursue teens and preteens), and about 1/3 are the "essential" gays some people are commenting about, who are lacking in masculinity possibly because of influences in utero (youngest sons of older women, that kind of thing).
Gay women are almost all head cases, as best I can make out; many psychologists believe it, too, despite 40 years of unremitting propaganda put out by the gay orgs embedded in the big APA's. [Of which there are three: Psychology, psychiatry, and psychotherapy.]
I agree that it obviously is the idea of the so-called 'bisexual'. Overtly.
But, it is true of homosexuals as well, and all MSM and WSW. They have been provided sexual outlets that will be repeated and some consistently repeated. A male stuck in pre-adolescence where girls are scary and rejection is the worst thing possible, all the way to those who are titillated by some form of 'rebellion' or 'domination' or 'sublimation'.
And females, the same, with their sometimes bizarre rejection of males, but then seeking a dike relationship of 'male'/'female'. Totally weird. Strap-ons, artificial insemination, 3rd party insemination....all of which testifies to this being in the realm of accepted outlets.
