hypothetically if hypno-porn worked like that then god knows what else is coming, maybe people experiencing it were already transgender but weren't able to express it, i think porn kind of legitimates it & works as a confirmation bias that yes it could happen, getting addicted to porn is wide spread happening but changing sexual orientation due to watching continuous porn is difficult to digest. if thats the case then watching mission impossible or sherlock series might turn one into a spy or detective. also identity crises, mental health, family conditions may play a vital role in understanding such issues.
