I think a lot of directors and actors want to be in porn, but not have the stigma of being in porn. Because those long, unnecessary sex scenes ARE porn, just with careful bribes and camera angles to make it airable.
Because if they wanted to just add titillation, there's much better ways to do it. Easy ways, too: Costumes, camera angles in action (or even passive) shots, character traits, many ways to entice the audience, that can be done at the same time as plot progression, saving the audience's time and the film's budget.
