How do orgasms affect men's bodies?

Orgasms start in men's genitals and pelvic regions. Muscles in those areas and throughout the body (often in the face and rectum) start to contract in a rhythmic pattern. The penis and ejaculatory ducts become swollen and contract. As men orgasm, they often ejaculate, which means that sperm-filled semen travels through the urethra and out through the tip of the penis. While this is going on, other areas of the body also respond - heart rate quickens and breathing becomes heavier. Brain waves change and produce hormones like oxytocin and endorphins, causing a pleasurable, relaxed feeling throughout the body.
