I get she was uncomfortable, but i thought that's how they film all sex scenes? I've seen people grabbing on kissing on titties in lots of movies. they're not naked?
Sam jackson even commented once that it's uncomfortable doing sex scenes because if you get a boner its awkward but if you don't get one then the actress gets insulted.
She saying Wesley pressured her, but he may have just been communicating the pressure he himself felt from the producers to get the scene right. doesn't necessarily mean he was trying to use that as an excuse to grope her in from of a room of film crew.
To me it just sounds like she was uncomfortable doing a sex scene and should not have agreed to do it. ultimately its up to the producer and director. I seen other people blame the costar, and realistically, ya'll not in a real realationship, so of course you might not have any real chemistry fukking (or simulating the act of fukking) on camera.
Nia Long made a similiar complaint about Cuba Gooding jr on boyz n the hood. he said he was just as uncomfortable as her filming the scene too. Wesley might be a bigger actor but ultimately he is in the same shoes as jlo.
