>>40609716They're bi-phobic, I'd say. Homos are fun because they can't get "pranked" by fragmentary homo tendencies.
They do not like the idea that this supposed big-boy top guy ALSO fucks around with males. He sees penises, filleted into inside-penises or just abject, visible ones (standard issue tranny gock).
That can give her the same insecurity as a transwoman; "is there something masculine about me you like?"
And, worst of all, she has to now stomach a potential "bottom" man and a larger pool for her man to choose from, meaning more competition.
