Not really. Viagra does have a limite effect on women but as their arousal mechanisms are not based on erectile tisue to the same extent as men. There is a new drug being tested in nasal spray form (!) which acts on the brain rather than the plumbing, and this seems to be more succesfull.
Generally speaking though this kind of approach is not really suitable for women. Chocolates, flowers and some understanding and sensitivity are far mor elikely to work.
