The four-year non-itch

Gosh, here's a shock:

A woman's sex drive begins to plummet once she is in a secure relationship, according to research.

Researchers from Germany found that four years into a relationship, less than half of 30-year-old women wanted regular sex.

Conversely, the team found a man's libido remained the same regardless of how long he had been in a relationship.

Of course, the man man may want sex as much, just not necessarily with the same woman he's married to. Another shock, I know.
