That's the first time I've ever heard anything like that. The result of every scene depends upon the performer, her co-stars, the content they are shooting, the length of the shoot/amount of re-takes, and experience levels. I've never had to "recover" for more than a few hours after a shoot... To my knowledge neither have any of my girlfriends in the industry. If female talent required a 2 wk. recovery period after every scene-- we would never get anything done. When shooting for larger companies models usually travel and stay for a few days to a week or so, shooting multiple scenes over that course of time. Even after intense guy/guy/girl scenes I've done, the most I really need is just a good snack and a nap, lol... I don't tend to shoot anything that would injure me in such a way that I would need weeks to recuperate. Professional porn stars know how to fuck, there are ways to have intense, raw, energetic sex that doesn't harm the female....or male for that matter. That claim seems extremely dramatic to me.
