This is an interesting perspective...
The math on the Paul McCartney-Heather Mills divorce is as follows:
After five years of marriage, he paid her $49 million.
Assuming he got sex every night during their five year relationship (which would NOT have happened!) it ended up costing him $26,849 per time.
On the other hand, Elliot Spitzer's call girl, Kristen, an absolute stunner with a body like no other, charges $4,000 an hour. For anything!
Had Paul McCartney 'employed' Kristen for five years, he would have paid $7.3 million for an hour of sex every night for five years (a saving of $41.7 million).
Value-added benefits are: a 22-year-old hot babe, no begging, no coaxing, never a headache, plays all requests, ability to put BOTH legs around you (!!!), no bitching and complaining or 'to do' lists.
Best of all, she leaves when you're done, and comes back when you ask her to. At 1/7th the cost, with no legal fees.
Sometimes renting makes far more sense.
