Zpenis Boner is a z-image turbo lora made for high res image render of naked men with erections. Its not as amazing as my dong-max-pro qwen model or my flux models but it renders really fast due to the nature of z-image-turbo. Its ideal at 1024 x 1536 or 1280 x 1920. If CFG 1.0 doesnt work you could move it up to 2.0. CFG 1.8 with 12 steps is real good usually
