Resolution and refraction After ejaculation, the penis begins to lose its erection. About half of the erection is lost immediately, and the rest fades soon after. Muscle tension fades, and the man may feel relaxed or drowsy, according to Ingber. Men usually must undergo a refractory period, or recovery phase, during which they cannot achieve another erection. This period is variable in men, says Ingber. In an 18-year-old, this is typically less than 15 minutes. In elderly men, it can be up to 10 to 20 hours. The average refractory period is about half an hour. Men differ from women in that men usually are satiated after one orgasm. Women can experience more than one orgasm with no loss of sexual arousal, and do not have to undergo a refractory period.
There are a whole bunch of places on his body (besides the shaft of his penis!) that are supersensitive and can lead to a mind-blowing experience. For starters, work the area around his penis — his balls, obviously, the scrotum, and the perineum (that place between his balls and his butt). Feel free to let your hands roam over other sensitive areas around his body, too — like behind his knees, his butt, and his inner thighs.
Some couples say that performing oral sex on each other helps them feel closer, says Dr. Rosser. But research suggests that people often engage in oral sex even if they don’t really like it, especially women. That 2016 Canadian Journal of Human Sexuality study, for example, also found that men were significantly more likely than women (52% versus 28%) to report that giving oral sex was “very pleasurable.”
Nancy Friday's book, Men in Love – Men's Sexual Fantasies: The Triumph of Love over Rage, suggests that swallowing semen is high on a man's intimacy scale. The man receiving fellatio receives direct sexual stimulation, while his partner may derive satisfaction from giving him pleasure. Giving and receiving fellatio may happen simultaneously in sex positions like 69 and daisy chain.
