Stable diffusion: Although on the first look the result seems nice, a particular detail is definitely wrong. What did I do wrong? Do I need to use a special SD model that knows that "18 year old guys" have a penis? Or do I have to mention the penis explicitly???

it helps to both use the explicit wording and a model which is designed for male bodies, since most of them are done for female images. Also if you like the image but the dick came out wrong you can "inpaint" the dick and fix it, same for faces.. see the original example vs inpainted
