A realistic, muscular young man with a serious face stands naked in front of a mirror, holding his thick, hard penis, which measures about 16 cm and is crooked to the left, with visible veins. He has short, dark hair, a trimmed beard, and a confident smile. He wears large black headphones and a smartwatch on his left wrist. His skin tone is brown, with a natural, healthy glow, and veins are visible on his arms. On his right shoulder and arm is a large, colorful tattoo of a female comic book/anime character. He holds a black smartphone with a gold case in his right hand, taking a selfie. The setting is a simple locker room with a tile floor, gray walls, and a yellow door in the background. The mirror has slight smudges and dust, making the scene even more natural and authentic. Highly specific skin texture, realistic lighting, realistic anatomy, and an ultra-realistic photographic style are used. Nothing is hidden around his penis, so it looks very real, and he also doesn't wear earrings, so it looks as masculine as possible.
