You probably already know about the rise in popularity of AI NSFW content creation.
You know what I’m talking about… Those awesome AI image generators that allow perverts, just like you and me, to instantly create extremely sexy, realistic adult images, all with nothing more than a few strokes of your keyboard.

 

But one problem pervs like us often run into is that the image generator doesn’t come up with exactly what you’re looking for.
Imagine this: you ask the adult image generator to spit out an image of an alien with massive tits.
Et voila! You get an image of a human-looking female with green skin and big, bouncy titties…
But is it exactly what you wanted to see? Does it look too human? Is the lighting right? The background? Are there other details missing?

 

Most of the time, what an NSFW image generator spits out is just not what you had in mind.
This is precisely where NSFW prompt engineering comes into play.

And that’s why we’ve decided to put together the following guide on how to create hyper-realistic adult images, exactly the way you want them, every time, and all while you avoid an unhappy walk through the so-called uncanny valley.

 


The importance of detailed prompts for NSFW content generators

When it comes to AI image generators, they do their best. But they’re definitely not perfect.
After all, they can’t know precisely what you’re thinking, what you want the scene to look like, and what you’re expecting from the finished picture.

 

And that’s precisely why you need to be as detailed as possible when prompting an AI image generator.
Going back to our example, if you ask a generator to create an image of an alien with big tits, that’s easy…

But what EXACTLY do you want the alien to look like? What color should her skin be? Should she have insect wings? Antennae? How many legs and arms?
Should she have a happy, sultry, or angry expression on her face?

These are all factors that an AI generator needs to know if it’s going to produce something that you want it to.
But what are the most important factors to include in your AI prompts?

 


Key factors to include in your prompts

 

There are no right or wrong answers to what information you need to include in your prompts. But the more details, the better.
So if you want an AI generator to produce ultra-realistic hot content, you might want to include key factors in your prompts, such as:

 

  • Lighting and shadows – Lighting can play a huge role in the look and feel of your AI-generated images, essentially changing the mood and atmosphere of what you’re looking at. You can make a scene look darker and sexier just by playing around with different lighting levels.
    Background imagery – Want to see an alien with massive tits? Great! But is she on the moon, on Mars, or in your living room? Make sure to include details about the image background that you have in mind.
  • Image texture – Going back to mood and atmosphere, image texture can also be important. Do you want your image crisp and HD, grainy, old-timey, etc. Nothing wrong with wanting your AI adult content to look and feel like it’s vintage.
  • Anatomy details – Obviously, you know what kind of body you want to look at. So you might want to include details like skinny, thin, thick, large, saggy, tight, etc. Whether you’re asking the generator for an image of a man, woman, or big-breasted alien, be sure to include as many details about their anatomy as possible.
  • Facial expression – This is just as, if not more important, than any other detail. What type of expression do you want your AI-generated image to have? Sexy and sultry? Sad and woeful? Angry and ready to pounce on you for a sexy make-up romp after a fight? It’s your call!
    Body language – Without prompting it, your AI generator won’t know what to do with the body in the image it creates. So make sure to let it know if you want your CGI to be standing, sitting, laying on its back, on its knees, etc.
  • Clothing and accessories – Whether you want your AI image in clothing or not is completely up to you. But if you do, make sure to include details about what type of clothing they should be wearing, such as short and skimpy skirts, tight shirts showing off muscles, lacey and see-through, denim, etc.
  • Fantasy scenarios – You’re free to imagine and explore all sorts of different fantasy scenarios, even if they’re somewhat otherworldly such as alien orgies, hyena hybrid lesbian women, or literally anything else you can imagine. Just remember that if you want the output to be ultra-realistic, you’ll still need to include other details like the others mentioned above.

Obviously, these are only a handful of factors you might want to include in your prompts.
Just remember that the more detail you give it, the better the AI will be at spitting out what you’re looking for in an ultra-realistic HD way.Otherwise, you might wind up taking a walk through the so-called uncanny valley…


Avoiding the “Uncanny Valley” effect with AI-generated erotic images

One of the biggest problems with AI-generated content is that people sometimes experience a psychological phenomenon called the “uncanny valley” effect.

Basically, this is when a person experiences a feeling of disgust when they see AI-generated content because of how realistic some images can be.And when it comes to the adult images that you want to generate, disgust is definitely not something that you want to feel, right?

 

So, how exactly can you avoid the “uncanny valley” effect?

Well, this is precisely where NSFW prompt engineering comes into play.
See, when you prompt an AI porn generator, it really will do its best to generate an image that resembles what you’re asking of it.

 

But the thing is, your AI generator is basing its output on millions and millions of images that it already has saved in its database.

So there’s a high chance that it might mess things up, blend different body parts into each other, or just spit out an image that will, indeed, give you the shivers, otherwise known as the uncanny valley effect.
On the other hand, the more precise you are with your prompts, the more likely the AI will generate something more realistic and in tune with what you’re looking for.

 

So if you want to avoid taking a stroll through the uncanny valley, make sure you’re as precise as possible with your prompts.
Providing as many detailed factors as possible, just like the ones we’ve mentioned above, ensures that you’ll get hyper-realistic adult content miles away from the uncanny valley.

 


Experimenting to find out what works and what doesn’t

 

Finally, it’s important to realize that you’re going to need to experiment with your prompts to find out what does and what doesn’t work.
So get to it!

 

Try prompting an adult AI image generator with a detailed explanation of what you’re into and see what it comes up with!

If you don’t like it, try and try again!
The more you learn from your past NSFW prompt mistakes, the better your results will be in the future!
