Original vibe of both Corbin Fisher and Sean Cody was that hot guys can be turned bisexual.
That's why in their write-ups they were claiming how much they were enjoying fucking and sucking each other instead of making write-up how atrocious it was for them and how traumatising etc.
The model was a guy who like purely physical sex with other (masc) guy but prefer pussy and only date women.
The only reason why they didnt promote models as bisexual is due to fact how male bisexuality is viewed by population and viewer's self loathing- a lot of people think bi men are just gays in denial and gays are supposed to be effeminate and not attractive which created this effect.
