Missed this one 'til now. IMO the answer (for women who are seeking an answer) is simple: birth control. 
Have your fun, but when it comes to creating new humans choose your mate(s) very carefully.

Birth control has no absolute guarantee of doing what it promises on the tin. Unless, I suppose, there's so much doubling up of effort as to remove the fun part altogether and render the effort pointless. Just like the relationship between photographic art and GAS.
In the end, it (sex) slips down the list of priorities and other values become much more dominant. Or worth clinging on to. Either way, I'm sure it's a better alternative than sleeping pills, so certainly not to be discounted. Sells a lot of fancy lingerie, thus providing work for photographers and advertising agencies, and, by coincidence, bringing in the need for even more birth control. I wonder if that's Victoria's dirty little secret? Or, on the other hand, Victoria's civic duty?
