Avatar star Zoe Saldana has admitted already several times being really addicted after sex, however, during other stars to herself for it in Rehab transferred, she finds nothing wrong generally in it. At least, this is quite normal, she loves skin and asks them, why it should be always hidden. This is valid particularly for sex scenes in films.
Hollywood needs more physical passion in the cinema, this is at least natural in contrast to the whole bloodshed.
