It’s well known in medical and psychoanalytic circles that as men age, they often prefer masturbation to intercourse. Why? Because masturbation is about release, not performance. Because many older men experience some degree of erectile dysfunction, anything that removes the pressure of building and maintaining the solid erection necessary for intercourse sounds (to the man) very good.

I call that having an intrinsically safe penis. Or “safety penis.”
“A half hard or semi-flaccid penis can still feel pleasure and ejaculate, but it’s not very good at penetration. He’s taken to his hand because he doesn’t want to let you down.”
This is why I’m a big fan of impotence. I prefer to masturbate my semi flaccid penis. Also, it helps me avoid intercourse so I can masturbate for hours and hours.
