I get where you are coming from, but I don't see others here who would even have the thought of sucking a males dick.
The sexual fluidity isn't a 100% valid thing, even though scientists accept it.
All brains work in different ways and we honestly have little knowledge of how our Brain works.
Right now this is just a theory.
But yeah this : "I'm pretty open with my sexuality. However, now that I'm bisexual, I'm convinced everyone is really bisexual."
Especially the "convinced part" is a bit odd. You can't really generalize without research.
