YOLO said: sex in my opinion is, and should be for procreation, and nothing more, whilst i will admit a great many these days see sex as something for leisure, i do not have that experience, nor do i think it wise, in a civilised and polite society such baser urges should be striven to be resisted,
as for masturbation, that i rather find to be a disgusting practice that makes me feel dirty and serves no purpose at all, far from bieng pleasurable, it is a distraction that should be discouraged,
Yolo has been beaten up by many here, and while I agree with these criticisms I wish to add two things.
First, as to sex being only for reproduction, I would recall two things. First, human reproduction is inefficient and according to demographer Christopher Tietze, it requires an average of 16 matings to produce a recordable conception. Why are we so inefficient - cats just require 1 mating? The second thing is the reason for the inefficiency. In Robert A. Heinlein's book, “Stranger in a Strange Land,” earth visitor Valentine Smith calls sexual intercourse by the name “Growing Closer.” That is exactly why intercourse is inefficient - it is a mechanism for couples to enjoy each other, to demonstrate their love for each other, in other words, to grow closer, and stay close. Stable matings tend to produce successful offspring. So, evolution creates a situation that keeps mates - and families - together. In both sexes I believe it keeps us psychologically balanced by repeated touching by another human being - a psychological requirement (see Ashley Montagu's book, “Touching”).
Second, when intercourse is not available, masturbation keeps us sexually alive and active. This is important in women to maintain their bodies and sense of well-being (although I certainly would defer to women on this question). In men, occasionally emptying the prostate makes for a happier man as well as possibly reducing to some degree the risk of prostate cancer and other problems.
In sum, I disagree with YOLO and will continue to pursue a life of sex and masturbation until they fix the last screw in my coffin. I hope YOLO finds happiness, if not in the natural sexual activity that is a joy of our species, then in something else beyond sackcloth and ashes.
