Of all the problems in today's world –
phimosis would be the easiest to resolve.
There are many degrees and combinations of the different forms of phimosis. In Germany phimosis was found in 8.8% of boys . However, this statistic excludes figures for short frenulum; or for relative phimosis, which can only be observed during erection. Statistics for short frenulum are only measured in boars at 5.7%  and bulls at 2.1% . Although the os penis is a different structure, phimosis is also problematic and farm animals are monitored by the British Breeding Association because "Copulation failure in food animals can be economically devastating to producers."
The most prestigious and influential study in the English-speaking world gives statistics between 1% and 2% . It was conducted over a period of seven years, with boys being monitored and educated about foreskins every year. The doctor who wrote the study reports this, but did not take into account that his monitoring and education clearly raised awareness, and in turn that this may well have encouraged the boys to experiment with and stretch their own foreskins.
It is common medical knowledge that phimosis causes pain and difficulty when retracting the foreskin. This often happens at the beginning of puberty or during first sexual intercourse and is the main indication for circumcision. These painful and difficult sexual experiences have hardly ever been researched. Why does our culture allow such painful difficulties to happen in the first place? Even if treated promptly, such spoiled and painful first intimate experiences are guaranteed to leave disturbing memories.
However, maybe such cases are the lucky ones. Psychological research never mentions that healthy, non-masochistic boys avoid pain and difficulty and thus develop avoidance behaviours. In 1990, Beauge  described the mechanics of masturbation with the avoidance behaviour inherent with phimosis. He never discussed the sexual fantasies associated with these forms of masturbation. But his research proved that gentle stretching of the phimotic ring can usually alleviate the anotomical condition.
Even in early childhood, a young boy with epithelial adhesions sticking the foreskin to the glans, will avoid the pain (and danger) of forcefully breaking them. Whereas an uninhibited boy will freely pull on and play with his ‛bottle nose dolphin’ in the bathtub.
Following puberty, the anatomical inhibition of the foreskin has a direct and active effect on self pleasuring behaviour. Phimosis preconditions the sexual behaviour, fantasy, and the consequent social behaviour.
Each specific phimotic condition has a specific effect. Masturbation in the flaccid state does not support penetrative fantasies. The potential pain of the frenulum or relative phimosis stimulates and associates with subconscious fear of sex. A tighter phimotic ring directly restricts stimulation and awareness of the glans – and though imagination plays the largest role in sexual matters, if the corporeal self-awareness is limited, then the imaginative fantasy will also be limited. All these conditions physiologically inhibit the full and normal potential of the anatomical member, and a psychological attitude of openness, versatility, and fulfilment in sexual fantasy and behaviour.
Phimosis stimulates and supports all forms of non-penetrative, inhibited and deviant sex from dominas' slaves to paedophilia. Basically, it reinforces tendencies towards loneliness and confusion, and it wastes love.
This is a deeply seated chaos factor in our culture. And these days it's senseless: The modern solution to phimosis would be a few drops of an enzyme solution to release any stubborn painful epithelial adhesions between glans and foreskin, at an early age. This would enable infant boys to play with and stretch any tightness out of their own foreskin.
This has never been researched, however there may be a starting point in the anthropological literature, with Bryk's account of Tahitian boys, who make use of the urine collected in the pocket of the foreskin to loosen up their own adhesions . The separation of these adhesions "results from keratinization of the cells under the influence of androgen". Urine is rich in androgen. So a few drops of an androgen enzyme solution at an early age would allow boys to self cure this problem.
The earlier a boy can develop a pain-free, comfortable relationship with his essential physical and anatomical masculinity, the greater the chance is that he will develop a healthy sexual relationship with himself and others.
