La Gringa-
You, my dear, are the exception and not the rule. It is a widely know scientific fact that the majority of women have a marked decrease in sexual drive after the "honeymoon phase" of the relationship has passed. It has nothing to do with the male trying to impress her. His desire to impress goes on for years after the "honeymoon phase" has passed as he desperately tries to get the sexual component of the relationship back to the "dating sex" degree of passion. Women use sex in the early stages of the relationship to capture and keep a man until he can be coerced into a legally binding, life-long contract. Once that contract has been consumated, her need to fulfill
his needs is greatly diminished unless a major project around the house is on the horizon or she wants a new car/ house.
Once the man understands that the "dating phase" is gone for good, his desire to impress subsides because he understands that if he continues to satisfy her properly, it only prolongs the time span before he gets it again. He learns that it is far better for him to go ahead and get himself squared away during sex so that she is left unfulfilled on purpose. This tactic exponentially increases the possibility that he will get some again soon if she is left wanting. Women and sex are like camels and water. When most women have been completely satisfied, they can go for a long time between sexual refills (no pun intended).
A woman's sex drive usually doesn't appear again until she reaches the "need to reproduce" phase. But, once again, it goes dormant after that need has been fulfilled. There are some really good episodes of sex during this phase but once she has given birth, she's done for a while. In a perfect world, the "honeymoon phase" and "need to reproduce" phase should be spread out if at all possible to prevent an excedingly prolonged period between the first two stages and the final stage.
The dreaded final curtain call comes during the mid to late forties when a woman is at her sexual peak. Unfortunately this phase only lasts but for a few years. Scientists hypothesize that this is natures way of helping women try to kill their husbands prematurely with heartattacks in order to eliminate the risk of competition between the man and woman later in life when they need their children to care for them in old age. Once it is evident that this no longer works due to greater life expectancy, the woman relegates herself to the chore of trying to make the man's remaining years as miserable as possible so that he might take his own life. This is done so that assets won't have to be split (unequitably) in a messy divorce and she will have the un-divided attention of her children and grandchildren.
Do you know why brides are always smiling?
I will probably have to post the answer to this one in the adult section...
