Sasha Grey? Is that you? Are you still dating Vinnie Chase? I thought you broke it off with him.
Scandal.
Swindle.
Your boyfriend is basically a hypocrite. What's good for the goose isn't good for the gander. I'm sensing he has control issues and thinks that things are okay when he does it, because you can trust him and it's just business, but he doesn't trust you to know how to separate business and pleasure and also doesn't want any other man to have any parts of his body on you.
Insecure. That's what your boyfriend is, ESPECIALLY considering the line of work you two are both in. He can't trust you because he's got major insecurities. Until he gets to the root of those and accepts that you two are going to be doing something very similar acting.
Here's the thing for you though, if you're boyfriend's ego is more important to him than your career, you might want to consider the other areas this might eventually come up. And whether or not it's worth it to you to forego doing what the job requires to make him happy if he's not willing to compromise. It would be one thing if you both agreed not to do any scenes, but he's being hypocritical. What's more important to you? His ego and insecurity, or your career?
Only you can decide that.
This happened in my old performing arts school, except the genders were mixed around, and the girl didn't just say no to kissing. This poor guy wasn't even allowed to hug a female actress on stage. Same as with this question, his girlfriend was also an actor, so it's not like she was in a position to not understand how kissing someone as a character and kissing someone as yourself differ. And unlike this asker, the poor guy was too brainwashed by her to think that there was anything wrong with it. :(
