Nick Stahl was masturbating in a porn store

LA may have almost a murder a day and 1,000 rapes a year, but what they don’t have is grown adults in a store that sells pornography masturbating in private (because it’s better to have them try to memorize the porn and then race home with an erection), but ‘Terminator 3’ star Nick Stahl had to learn the hard way. TMZ says…

LAPD undercover vice officers were conducting a routine check of an adult store in Hollywood around 6PM — and found Stahl alone in a private booth, watching a porno, and committing a “lewd act.”
(He) appeared to be “touching himself” and he was booked for lewd conduct … a misdemeanor.

Honestly, what is the private booth with porn for if not masturbating? Who else would use it? Porn quality control agents?
