It&#x27;s not surprising. Part of it is that the sexual appetite is particularly powerful. Part of it is because people are often weak in being able to endure (not talking repression here) the appetite when it manifests. Add to that the fact that sexual desire, when routinely gratified, can be habit forming. Then add to that a culture that obsesses over it and enables mindless sexual indulgence. Funny because lack of sex never killed a man. A lack of food can. Yet the desperate some claim to feel around sex would have you believe they were starving.<p>When such a greater good demands we abstain and we don&#x27;t, we can justly be called selfish. It&#x27;s something one needs to work on and struggle. Instead of waffling between prudery and licentiousness, one should work on one&#x27;s sexual prudence (called the virtue of chastity, but the word, I fear, is uncool and infected with cooties, say the cool kids). It involves endurance, mindfulness, and possibly suffering.<p>Robin Williams once joked that god gave man two heads but just enough blood to operate one at a time. There&#x27;s something to that.
