Changes in Sexual Motivation with Commitment

There's a joke that the most significant substance reducing libido or sex drive in women is wedding cake.

A German researcher, Dr. Dietrich Klusmann from Hamburg-Eppendorf University Hospital, interviewed 530 men and women about their sex lives. 

He found that 60% of 30-year-old women wanted sex "often" at the beginning of a relationship; but within four years of the relationship this figure fell to under 50%, and after 20 years it dropped to about 20%.  In general, the longer a woman was in a committed relationship, the less she desired sex.

However, the proportion of men wanting sex "often" remained at between 60-80%, regardless of how long they had been in a relationship.  

Dr. Klusmann attributed these changes in frequency of desire in men and women as due to evolution.  There may be other factors, though.  Is this a culture thing, or an age thing?

I will admit that I find this a little unsettling.


  1. This seems to be serious research, and the reasons for this phenomenon should be discovered. For example, do long-married guys initiate the possibility of sex but do little in the way of romantic preparation?

  2. So then what are the cougars out there looking for?

  3. i would certainly say my own experience echoes those stats - i still want 'it' as much as i did the day i met her (wife), but she doesn't.

    (which is very upsetting to me, but no doubt my fault)

  4. So do women get tired of sex as they age, or get bored with their committed partners?

  5. I'm in there with Mark and Beach Lad.
