1. The front of a man mainly refers to the genital area, including the penis and scrotum.
2. The penis is a cylindrical organ located below the pubic symphysis. When not in an erect state, it is usually soft and attached to the abdomen, with the tip being the glans, which is more sensitive. During erection, the penis becomes engorged, enlarged, and hardened to facilitate sexual activity.
3. The scrotum is a loose sac located behind the penis, with testicles on each side connected to the body through the cremaster muscle on the scrotal wall. The main function of the scrotum is to protect the testicles, regulate their temperature, and ensure that sperm is generated and matured in a suitable environment. The surface of the scrotum is also covered with hair and skin folds.
