regardless of frequency, your marriage is more likely to be close. Both 
men and women occasionally have difficulty coming to a climax, only 
about 5% to 10% of men but 30% of married women only occasionally 
or never climax--another 30% of women consistently have orgasms 
(Michael, Gagnon, Laumann & Kolata, 1994). Women who are very 
happy with their marriages are much more likely to be orgasmic (but 
being non-orgasmic doesn't necessarily mean you have a serious, 
unconscious dissatisfaction with your relationship).  
There are remarkable variations in researchers' estimates of how 
many husbands and wives are unfaithful, ranging from 20% to 70%. 
Knox (1984) suggested that 50% of men and 20-40% of women have 
had an affair at some time. A more scientific survey found that 75% of 
married men and 85% of married women had been faithful (Michael, 
Gagnon, Laumann & Kolata, 1994) but these surveys include the newly 
married. In recent years, extramarital sex reportedly occurs about as 
often among women as men. Working outside the home increases the 
chances of an affair for women (Levin, 1975), about 50% of these 
women supposedly have had extramarital sex. Men seek casual sex 
and have more outside partners; women seek emotional attachment 
and have fewer outside partners (Blumstein & Schwartz, 1983). Some 
research suggests, as you would expect, that a poor marriage or 
unsatisfactory sex is often associated with unfaithfulness (Thompson, 
1983). According to Grosskopf (1983), from 50% to 70% of unfaithful 
women said they did it because they were emotionally and sexually 
dissatisfied with their husbands (35% had found out he had an affair). 
On the other hand, Blumstein and Schwartz say that many couples 
who have had an affair are just as happy with their marriages as 
faithful spouses. They also say having one affair doesn't necessarily 
lead to another and church goers are just as likely to be unfaithful as 
non-goers. Unfaithfulness has been discussed above.  
  
Sexual intercourse: It is making love 
Sex, if done well, generates positive feelings towards the partner, 
i.e. it "makes love." "Making love" is usually a natural, emotional 
experience, a part of a relationship, rarely just a physiologically 
pleasurable act. We are ordinarily very careful who we have sex with; 
it is a consciously planned and orchestrated act. Yet, interestingly 
enough, human sexual arousal is a primitive physiological response 
that can't be consciously willed, e.g. men can't just will an immediate 
erection, women can't will lubrication. One needs to generate sexy 
thoughts or physical stimulation; one needs to be relaxed and "in the 
mood," then penises harden and vaginas moisten automatically.  
It is tempting to say that making love is just doing what comes 
naturally, but that isn't at all true either. There are many things about 
intercourse we don't know automatically. For instance, we don't 
naturally take lots of time but good sex can't be rushed. We don't 
know what feels good to our partner, he/she has to tell us. In the
