Guys often pee after ejaculating due to the presence of the urinary sphincter which closes during arousal and ejaculation to prevent urination. After ejaculation, the sphincter reopens, allowing men to urinate and flush out any residual semen from the urethra, reducing the risk of infection. This is a natural physiological response aimed at maintaining urinary tract health.
