Senior sex: What changes as men get older? A need for more stimulation to achieve and maintain erection and orgasm; Shorter orgasms; Less forceful.
Men's Secret Sex Problem. Plenty of guys 50 and older experience difficulty with orgasm and ejaculation, says Dr. Louanne Weston, a sex therapist. "As men age, they notice that their penis needs more stimulation to trigger ejaculation," says sex therapist Dr. Dennis Sugrue.
Another normal change that occurs in the older man is the loss of orgasmic inevitability or the sensation of impending orgasm that occurs in younger men.
When men in steady relationships contemplate their sexual woes, erectile dysfunction (ED) is usually at the top of the list.
