Prompt

The proportions of the genitals look unnatural. While the thickness of the penis is ideal, please realistically depict a 21cm erect penis with a large glans and testicles, ensuring the balance is correct as per the initial prompt. Also, please adjust the image so that the penis is firmly gripped in a hand and pointing upwards: depict the moment of ejaculation, with semen spraying forcefully and dripping from the glans.The size of the nipples is perfect, but they currently look feminine: please adjust them to have a masculine shape.
