Adult films are not easy to make is this true?

I heard that the ultimate thing that a director trys to do in a adult film / is to get the entire cast up and into full blown heat ! at the same time and that this is not that easy to do. / and then the flluffs and other workers on the set have...

to control them to keep them in heat as long as they can in order to make a film. And the whole process is not easy !

Yes ,you are right it is not easy / but if the electricy is in the air / and the cast is ready/ They can go into HEAT from jump street ! But the big job is keeping them in HEAT long enought to make a film
