Usually when people talk about changing sexual orientation, it’s to turn gays straight but Marvel comics inverts that idea in Young Avengers #9.
It reveals that the reason Prodigy kisses Hulkling in the previous issue is because his superpower turned him gay! (actually bisexual but close enough) Prodigy explains that he can telepathically absorb knowledge and skills but accidentally absorbed “everything.” He describes it as an “awakening” to something that was always there.
The implication is that we’re naturally bi-curious.
