Yeah I don't see him acting like this because he can't get an erection. My guess he and Scarlett got fucked up and tried to film a scene and Ralph asked her to use a dildo or strap on on him. Once he was sober for 5 seconds realized the footage was on the laptop decided to steal it to stop Scarlett from leaking it. I can't think of anything else that could embarrass him and cause him to act like this, it's fucking Ralph we are talking about here.
