There are many who are puzzled to know what the Buddhist attitude towards sex is)))

(from 'Buddhism and Sex' by M. O'C. Walshe)

1. Buddhist avoids unlawful sexual intercourse, abstains from it. He has no intercourse with girls who are still under the protection of father or mother, brother, sister, or relative; nor with married women, nor female convicts; nor lastly with betrothed girls.
2. I undertake the course of training in refraining from wrong-doing in respect of sensuality.
3. Those inclined to develop a guilt-complex about their sex-life should realize that failure in this respect is neither more, nor, on the other hand, less serious than failure to live up to any other precept.
4. To refrain from all forms of wrong speech (which often includes uncharitable comments on other people's real or alleged sexual failings!).
5. Rigid puritanism and total permissiveness are extreme views, it is to map out a sane course between the two.
6. If we can experience the pleasure without attachment to a cause we are all right; if we become attached to it, we are not "hitting the mark." (sex, money, etc).
7. Divorce, like marriage, is a civil affair. Likewise, if a married couple decide to practice contraception, that is entirely their business.
8. Abortion is of course a different matter. Since this involves the taking of life, it contravenes the First Precept. It can only be condoned in cases of serious health hazards, where it may represent the lesser evil.
9. What, it may be asked, of "adultery," i.e., extra-marital sexual relations? The short answer is that, quite obviously, this is something to be avoided.... At the same time, there may be many reasons which make a dissolution impossible or impracticable. An extra-marital relationship in such circumstances may serve to make the situation tolerable.
10. Sex — like everything else — is a purely impersonal force. We tend to think of it in intensely personal terms, but in actual fact it is a force that just flows through us and uses our most wonderful and inspiring emotions for its own ends, which are totally concerned with the continuance of the race as a whole. The idea that it is just a private and wonderful thing between you and me is merely a part of our general illusion. Altogether, it is a prolific breeder of illusions. It can lead a man to think he has found the most wonderful woman in the whole world while everybody else is thinking, "What on earth can he possibly see in her?"
11. To the Buddhist, of course, sex is an expression — perhaps the chief expression. It is therefore quite logical that we should seek to bring it under control. The aim of the true Buddhist is to bring about the cessation of craving, and from the individual point of view there is no other reason for sexual restraint than this.
12. The four foundations of mindfulness as set forth there are: mindfulness as to body, feelings, states of mind, and mind-contents.
