You think the penus is rock hard like bone where it is really rock hard like a water balloon. Your penus contains cartilage like your nose or ears and these are floppy with a fair bit of give and this does not magically get stronger when erect it is exactly the same floppyness as normal. The hardness is blood and plasma and is just water pressure. Your body pumps water in and does not let it leave so the veins that leave the penus increases in pressure. So you have a water balloon and you think a vagina or anus are straight internally they are not. Google sex in a MRI machine and look at the images. A woman’s body parts are also floppy and can move around during sex. You can see in some images with a 90° turn and you would think you would notice it but no. So basically it probably does not matter.

Generally porn is a job just like any other. It is made up of humans so not everyone is going to be thair best selves all the time but most are. What you see is made up and edited. What you don’t normally see is the director and the performers going through a plan on what they are going to do before they do it but this can depend on the studio. Some studios have a shot by shot set of sex positions and a plan for the scene while others they may just start rolling and see where things go.

What stops things is the law and people taking. You probably don’t want to know the details but https://en.m.wikipedia.org/wiki/GirlsDoPorn where there are people in jail for a long time for sex trafficking, fraud and coercion.

There are also a few other cases where people talk out in public against a performer or a director and they will have a hard time getting work in the future. An examples of this are Jimmy lifestyles who was the director for wankzvr a few years ago. Alex coal made an allegation of something happening after the shoot and he is no longer working for the company and the company employs someone on set to make sure that everyone is acting up to standard.

If you are expecting you to just click go and have 10 pages of erotic stories then no it does not exist as far as I can see. Ollama is a tool to just download and run a llm on a computer and most models are designed to tell you to go away if you ask for anything like that. Some have been uncensored and do not have guardrails but that is not your problem.

A large language model is really advanced auto correct. We have taken all text we can, done some fancy statistics to work out what words are used neer each other and found what the average most common next word would be. Keep rolling the dice and work out what the next most average word is and repeat. A llm does not know what a word is and is based on converting combinations of words to a number and some fancy statistics to work out how common “th” and "e " are so it can spit out "the " randomly when it thinks it is statistically needed.

Llms cannot keep track of context and the more you use them thr more likely they will forget character names etc

IMDb does allow porn, you need to go through advanced search and enable it to find it but you can find it if you are looking. There is also more info that is hidden from the profile unless you have an industry account. I believe they allow it for this reason as there is no reason why a make up artist or camera person can start in porn and move to mainstream.

I would recommend you download files to a nas and use xbvr or stash + stash-vr-companion (a tool I wrote) or stash-vr and stream content to heresphere or deovr running on your headset.

Another of my side projects is timestamp.trade to share markers for xbvr or stash so you get the timestamps of each action crowd sourced from other users.

I am sure you are aware but eroscripts do have people make scripts for videos many are free so join the forum and look for the Google doc of free scripts.

The original version of this scene https://www.sexlikereal.com/scenes/time-stops-japanese-lolitas-19992 There is a group of people going after porn companies to try and cut them off from visa and MasterCard and trying to pressure companies to censor porn. The original version of the scene contained “stop time” themes and was removed from the site. An edited version was put back a year later with the story cut out and just the sex remains with huge edit jumps so a 1:22:20 scene became 38:13. There has been a fair bit of porn purged from the internet and censored a few years ago.
