When both partners agree on the types of sexual activity that is desirable there is usually little conflict. However, when one person wants sexual activity that differs from their partner's wishes, relationship problems may develop. Sometimes one partner desires sexual activity more often than the other partner, and this also puts stress on the relationship. We know that men and women can have differing sex drives. Men and women, for instance, both have a hormone called testosterone, but this is present in much higher amounts in men.
Women have high amounts of hormones called estrogen and progesterone.
Testosterone is known to cause facial and body hair and larger muscles, but it can also cause certain emotions, like aggression and increased sex drive. Young men, for example, have strong sex drives, most likely due to the increase in testosterone that occurs at puberty. Men are often stimulated by things like pictures, watching sexual movies, or looking at women they find attractive. Women, on the other hand, may become more aroused by words, intimate emotions, or signs of affection like kissing or close touching. By talking about these differences each partner can discuss, in a non-threatening manner, what she or he needs.
