8 Male Erogenous Zones You're Probably Ignoring During Sex
Penis health: Identify and prevent problems - Mayo Clinic
To get an erection, nerves signal a man's body to store blood in the vessels inside the corpora cavernosa. As blood fills the chambers, the spongy tissue expands and the penis stiffens and gets longer. During ejaculation, semen which contains sperm cells and fluids flows through the urethra and out of the body through the meatus. After ejaculation, the blood flows back into the body, and the penis becomes soft again. Sometimes, growths can develop on the penis that are abnormal but are not cancers. They are benign. These lesions often look like warts or irritated patches of skin.
Red spots? Fleshy bumps? When to worry about spots on the penis
Spots and marks on the skin or glans of the penis could be many different things, many of them easily treated or not especially serious.

Not all spots in this part of your body are caused by sexually transmitted infections, but some can be.
A penile rash is the presence of spots or sores on the penis and possibly on other areas of the groin or genitals. It can be accompanied by itching that may be intense, and pain or tenderness. Related symptoms may include blisters ; burning or pain with urination; redness, warmth or swelling; scabbing; and scar tissue. Penile rash can be extremely uncomfortable or awkward and may create difficulty with urination, sexual relations, and daily activities.
