Drug company Eli Lilly has been stealing market share from the world famous erectile dysfunction drug Viagra with their own erectile dysfunction drug Cialis a new research project could be shedding light on why this is the case

A study undertaken by a husband and wife decided to look into the relative benefits of both Viagra and Cialis by conducting a study with 100 sexually active couples over a three month period.

The idea was not to just look at erectile dysfunction from a man's point of view but also to get a lot of input and feedback from the women too.

One of the findings was that women prefer the Cialis because it works for a longer time and this means that sexual intercourse can be spontaneous as opposed to forced in the four hour time window that Viagra has.

Professor John Conaglen and Dr Helen Conaglen said that almost 80% of the women said that they preferred Cialis over Viagra thus giving a fascinating insight into the way that women react to erectile dysfunction medication.

The women specifically commented on the fact that the 36 hour time window that Cialis gives for enhanced sexual activity means that intimacy and foreplay are not hurried and thus any erection problems the man may have are completely forgotten.

This is not the first time that News about the greater intimacy achieved when using the Cialis as opposed to the Viagra drug.

The Viagra medication is associated with "having sex" whereas Cialis, is increasingly being known as the drug to use when you want to "make love".

So if you are a man who uses erectile dysfunction medication maybe you should speak to your wife or partner about how she feels about using it, and whether she might prefer you to use some other medication instead. Remember the key to good sex for woman is very often emotional and psychological and the simple act of talking about these things can often increase the sexual function and pleasure for a woman.
