"It's probably the most uncomfortable part of acting," Karan said during a visit to the IANS office here on Wednesday with the cast of the film.
Karan, who is seen getting intimate with both his co-stars Zarine Khan and Daisy Shah, also said that if such scenes are liked by everyone that means the actors have "done a good job".
"But if everyone is liking it (intimate scenes)... that means we have done a good job," he said.
Karan, who shot to fame with TV series "Dill Mill Gayye", where he played the handsome doctor named Armaan Malik, says he doesn't wish to do a daily soap at the moment as it takes up "too much" of his time.
"I am ok for doing season based shows, but doing a daily at this moment is not possible because that takes up too much of my time and that's 30-day minimum guarantee," the "Alone" actor said.
"Hate Story 3", which is slated to hit the theatres on Friday also features actor Sharman Joshi in a key role.
