Although the article sounded like some sponsored advert, that’s interesting and it seems like a step in the right direction. Although I am not an actor myself, I can imagine that it is not that easy to be comfortable doing a sex scene and having somebody on set that can make actors feel more at ease would definitely be a positive.
As to all the comments who say sex should be completely excluded from shows — I personally really do not agree with that. I do find shows that use sex as the main focus in order to attract the audience bland. However, in the same time, I do believe that in all the rest of the cases, when it adds to the story and the characters’ personalities, it can be an important element. Sex is part of our culture and lives and censoring it out completely in films is just creating an unrealistic representation of reality.
