AI porn images, due to the training data, favour a youthful appearance such as big eyes and rounded features, and scan a lot of the time as teenagers. Furthermore, there is an uncanniness to GenAI images where they don't register as fully alive. So yaknow, a pretty unsexy feature: an underage corpse.
I always specify at least 25 years of age. If you go lower, yes, you do get very young looking images. For example: "A cute 25 year old woman with long, thick, wavy blonde hair is standing on a crowded sidewalk...."
I've entirely stuck to images of adult actresses who are generally who the character was based on anyway.
