The quote suggests that intense desires often arise from deep cravings, akin to the overwhelming needs of imprisoned individuals. This hunger can fuel strong passions and fantasies, leading to a heightened sense of eroticism. In a seemingly ideal environment, such desires can flourish, presenting opportunities for exploration of one's sexuality.
However, the quote warns of the potential downside of unfulfilled hunger. If these desires go unaddressed for too long, they can lead to a sense of aimlessness or despair, exemplified by the metaphor of becoming a bum or tramp. Thus, while unrestrained longing can inspire creativity and erotic exploration, it also carries the risk of a detrimental outcome if it becomes excessive.
