Increase in blood pressure, heart rate: may have some secretion from bulbourethral gland. Increase in heart rate, respiration, blood pressure: male plateau phase, glans of penis darkens, swells, testes increase in size, testes elevate towards body, bulbourethral gland secretions appear and increase through this period, muscle tension increases. Involuntary movements occur: heart rate increases, respiratory rate increases. Involuntary muscle contractions, including pelvic thrusting: peak heart rate, blood pressure, respiratory rate, ejaculation does not always accompany orgasm.
