He'll probably be annoyed with me for posting this bit of tmi, but he gets far more erections, far easier, than he did at 18. I just wonder if the whole thing is because circumcised men don't just start lower on the spiral, but actually start going down it a lot earlier than intact men.
Our sexuality is determined and driven by many factors but the main ones are (1) instinct, (2) hormones, (3) physical pleasure and (4) physical or emotional attraction.
In a small child, none of these are present so they have little to no interest in sex but as they age and get to their teens, their bodies start producing testosterone in significant quantities. They have the instinct to reproduce once testosterone is being produced. This accounts for the suddenly emerging desire to have sex. If you looked at it from a totally detached viewpoint, sex is a pretty ridiculous enterprise yet from the viewpoint of the instinctual urge that we have all experienced, it makes all kinds of sense. That urge is kicked off and driven by testosterone. BUT, and that's a big "but," if there were no pleasure reward from it, we would all quickly loose interest. Without the influence of testosterone, the physical or emotional attraction would quickly fade as well at the first argument or during other hard times. It would also quickly fade if there were little or no pleasure from the act.
As the man attains puberty, his body is flooded with testosterone. The thinking is that it reaches a peak in the late teens on average. It's possible that in some men, it doesn't reach it's peak until well into the 20's. However, once it reaches that peak and plateaus for a while, it starts to decline. It's at this point that the pleasure reward would become increasingly more important to his interest and desire in continuing an active sex life into his later years.
If the research is correct and if my personal experience is valid and the reports of restoring men is correct, then circumcision does reduce the pleasure aspect of the sexual act. From research I have read and my own noodling out of the information, it is pretty clear that circumcision has a strong correlation with midlife impotency and I believe it is simply because of the decreased sensitivity and thus decreased pleasure the older man experiences. It just falls below the level of adequate and thus, he is not driven to the next pleasureable experience because he has no indication that the next one will rise above the "adequate" level to exert the effort involved.
One thing that I do believe has a significant influence here is the intensity of the emotional bond with his partner. My experience is that as I become more emotionally bonded with my partner, the satisfaction from the sexual experience also improves. This may serve to somewhat replace the lost pleasure and continue the desire for a sexual relationship.
