That settles that. Here's a better question, how real are those videos when a JAV star shows up at a random fan's house? I'm sure a JAV company doesn't want someone in a video who'll last a minute with her, there's gotta be some vetting of the male talent they choose.
Supmop> It's not an STD issue, but more of an issue of how the fan would act. Actors are dependable and can cum when needed. Most people who post in forums like these or make comments on tube sites proclaiming their massive erections probably couldn't even sport a half-stiffie with tons of lights all over them and a production crew all impatiently waiting for them to finish.
There was an HIV issue a few years ago in US porn, but it was just 2 people. Both US porn and Japanese porn are really strict in testing.
That random kinda cute girl at the club has a better chance of having an STD than an AV star or a porn star.
