Momus, as you creep into late middle age, do you fear impotence at all? After all, erectile dysfunction can be a significant problem for men in their fifties. Erections can take longer to occur. Even then, they often require direct manual stimulation, and may be not quite as firm as they used to be. Also, the urge to ejaculate may be not as insistent as in your thirties and forties. Nor is the force of ejaculation as strong. Desire for and frequency of masturbation may lessen as well. The testicles often shrink too, and the scrotal sack drops. And the sack doesn't bunch up so much during arousal for fifty year old men. Just wondering if any of this worries you at all, Momus? Or are you Zen-like in your insouciance, faced with these bodily changes?
