Men generally do not have a specific age when they stop being sexually active; while frequency and desire may decrease due to age-related factors like hormonal changes, lifestyle, and health conditions, many men remain sexually active into their 70s, 80s, and beyond, with roughly 63% of men over 80 reporting continued sexual activity in one study. The "how" involves overcoming potential challenges such as erectile dysfunction, which is often treatable, and understanding that lifestyle choices, mental health, and open communication can significantly influence a man's continued sexual well-being.
