I often find myself silently debating the finer points of sex while doing the sorts of task that require minimal attention. The pros and cons of orgasm is a perennial favourite. I occasionally dwell on my continued inability to recognise any difference in behaviour or attitude in either myself or my wife following periods of no orgasms or many orgasms, which I suppose helps justify our continued enjoyment of them. The other day, though, I found myself wondering what, precisely, the point of orgasm was, its purpose, its reason for existing. For men, since orgasm and ejaculation go hand in hand, the matter seems obvious. Procreation of the species depends on it. The rush of pleasure ensures delivery. For women, it's not so obvious. Sex need only be sufficiently pleasurable for them to want, or be willing, to engage in it often enough to get pregnant. Why, then, do women have the capacity for far greater pleasure, over and above what is necessary? What evolutionary purpose is served by something that appears to have no other underlying motive?
I find it hard to believe that the capacity for orgasm - which is a pretty extraordinary event, however it's viewed - can have evolved on a whim; and, assuming it didn't, I suspect it shouldn't be given up lightly.
