This is a very popular site viewed by countless directors and industry insiders who probably use it as a bible regarding what is going on in the European Porn Industry.
One of the things that has always surprised me is that this question has never been asked on here. I saw this question asked on a private forum before about Porn scenes and the results I used as a very good measure of what not to do when scripting for website scenes.
Given that so many people who have the ability to change scenes are viewing this content then why not state what you do not like to see in porn movies. Your probably more likely to purchase a scene if it does not contain stuff you hate.
I'll start off with the most popular ones on the post from the private forum.
1. Nutsack cam. People don't like seeing a big sack of balls bouncing around covering up the areas that are more appealing. Stop with the close ups on guys nuts.
2. False boobs. There is still a preference towards natural models over the "silicon barbies" (I found that interesting as the forum I found this on was a US one)
3. Spots and pimples on ass. It was agreed that a girl who has an ass covered in large spots, pimples and sores is generally not appealing and a turn off.
4. Over talking. Models who talk and scream throughout the entire scene can get irritating. Surely there is a limit on the amount of time a model needs to say or shout "yes".
5. Like a log. Models who just lie there like a log and don't actively participate in the scene are just a major turn off.
6. Silence. Complete silence from the model until the very end when she suddenly errupts into a totally fake orgasm is rather annoying.
7. Sudden scene changes. Sometimes a scene is building up to a big finale with the action getting faster and faster when suddenly the cameraman (or editor) changes to an earlier scene where the action is completely different. Way annoying.
8. Continuity. We have all seen this. One moment the model is fully dressed and the next totally naked with no actual striptease. Sometimes its worse and the model will suddenly end up wearing items of clothes again that she already removed. Show the striptease and when clothing is off.. keep them off!
9. Absolutely horrendous overdubbing. Tons of scenes are dubbed over to remove the models actual noises and rather strange pathetic overdubbed noises are added (that sound more like someone chopping wood than fucking). There may be a ton of languages in the world, but "uhh, uhh, ahhhhh"... is universal... keep the original audio during the fucking scenes (fine to change it during the non sex areas).
10. Scenes that are shot in dark locations with non adequate lighting. Okay, I understand the need for atmosphere and stuff, but this is not hollywood. Its a porn movie and we want to see whats going on not just hear it. We may switch the lights off at home to fuck, but hell we don't pay to see the same on tape!!
Those were some of the most common. Anyone care to add.
