Madeleine M. The process of ejaculation begins when a guy is sexually aroused, often -- but not always -- from the direct physical stimulation of his penis during touching, rubbing, oral sex, or intercourse, for example.

Unlike the female genitalia , the male reproductive organs are on both the interior and the exterior of the pelvic cavity. They include:. Sperm production occurs in the testicles.

The penis grows enlarged and firm, the skin of the scrotum is pulled tighter, and the testes are pulled up against the body. As sexual arousal and stimulation continues, the glans of the erect penis will swell wider. As the testes continue to rise, a feeling of warmth may develop around them and the perineum. With further sexual stimulation, the heart rate increases, blood pressure rises, and breathing becomes more rapid.
