In most of the country making porn is illegal but possessing it is not. One place in particular is Van Nuys California where it is legal to make it so if you are going to try to use this defense I would start off there. The massage thing has worked for some in the past but typically if you end up with a hooker then you don't end up at the police station anyway. It is the time that you end up soliciting a cop that gets you cuffed. They have to legally get you to say that you are going to pay her to have sex with you. You incriminate yourself by agreeing to pay a certain price for a certain sexual act. I doubt that you would get a cop to agree to shoot a porn film with you. But if you do send me a copy.
