He is so comfortable with taking his clothes off for the cameras he even claims it is the easiest part of his job.
Kutcher added: "Getting up close to the actresses is the simple part. That is some of the easiest acting you have to do."
The 'Punk'd' star has several intimate encounters in his new movie 'Spread' and although Demi visited him several times on set, he insists she has no problem with him getting naked.
He recently revealed: "You go to a movie and you have to shoot somebody with a gun and you've got to murder somebody in the film. When you go home, your wife doesn't think that you're a murderer, right?"
"You go to work and you have a scene where you have to portray having sex with somebody, your wife doesn't think you're going to work having sex with somebody. We're both in the same craft. We understand what our job is, and we do it."
