(Preface: I am a fan of anal porn and anal sex. I even have no problem with prolapse porn. This is something I'm curious about because so few performers are on the record discussing it, and I realize that much of the current information on prolapsing in porn is basically anti-porn propaganda from the right.)
(Second Note: Read the whole post before responding. I'm not asking, "Why is prolapse porn so popular?" or anything like that.)
Anal Prolapsing: at one time it was reserved solely for girls who did it naturally due to existing medical issues or girls who had performed one too many double anal scenes along with their regular anal workload. (Ava Devine, Amy Brooke: we're looking at you.) Now, we're seeing much more of it on screen, even from performers who are fairly new to the industry.
One could argue that rougher anal scenes and more anal scenes over a performer's career are changing things, but I think this is wrong. If that were the case, then the great anal queens of the late 90s and 2000s (Aurora Snow, Katja, Belladonna, Ashley Blue, Bobbi Starr, Sophie Dee, Gauge, Flower Tucci, Aurora Jolie just to name a few) would have prolapsed on camera years ago. Conversely, there are a number of performers who are young and have been in the biz for only a year or two (these ones I'm having a hard time remembering but there's a few who have done a lot of work for Evil Angel) and are between 19-22 who are already partially or completely prolapsing on camera. Anal scenes have obviously gotten rougher since the 70s/80s, but I think they've remained pretty consistent for the past 10-15 years.
Assuming that there were a. as many anal scenes and/or dedicated anal perfomers 10 years ago as there are now and b. that anal scenes have not gotten significantly rougher in the past 10 years leads to the following conclusion: many anal performers have been prolapsing off-camera before now but are now only showing it on screen because it has become acceptable and there is a growing market for it.
Jada Stevens is prime example. She has partially prolapsed in two scenes. In the earlier one, she's blatantly struggling to avoid a visible prolapse while expelling a creampie. First she tries to do it without having to gape her ass at all, but then she settles for just trying expel the cum without having her ass fall out. The whole thing appears to have been unplanned. (In the more recent scene she seems less concerned.) Amber Rayne is another one; I've seen her partially prolapse after a creampie once, though there was a recent Kink scene where they cut just as one was starting to happen. I've noticed this sort of thing from other anal starlets trying to gape but appearing to be holding back, perhaps to avoid a visible prolapse as well. Given how good Jada and Amber are at hiding it most of the time during somewhere between 50-100 anal scenes each, I wonder how many other performers (many of whom have done as many or more scenes) are doing the same thing.
I'm mainly curious because so few anal performers are on the record regarding this subject. Even the great Tristian Taormino has been strangely silent on the matter. I would assume that the performers don't want to share the gory details, and Tristian is reluctant to imperil her livelihood as an educator and director by challenging her main thesis: that anal is 100% safe, especially when performed by experienced (sober) professionals like porn stars, and that frequent anal *reduces* the chance of anal muscle weakness and prolapse.
My questions:
1. Have long-term performers who rarely prolapsed on camera been doing so off-camera before now?
2. Does "porn-level" (frequent, large insertion) anal inevitably lead to prolapse, despite most/all performers claiming otherwise?
3. If not, are the women who are showing signs of prolapse cutting corners or out of the norm in some way? (Drugs, not warming up enough, doing more scenes before things are healed, doing lots hard anal off camera, etc)
4. Does the prolapsing pose a long-term health risk? I remember some time back that Ava Devine claimed that everything is in great condition despite the state of her rectal muscles.
