The dream of Viagra, as shown in the TV and magazine ads, is of a long-married couple taking advantage of its pharmaceutical magic to deepen their long, committed, and fruitful relationship. This is the romantic story of Viagra, and in many cases, it's probably not too far from the mark.
Viagra's reality, though, is a lot more interesting and a lot more varied. Plenty of seniors, both married and unmarried, are finding that Viagra is enhancing their ability to have casual sex. Reports are that nursing homes are more active than ever. Young people without erectile difficulties are taking it to boost performance, get harder, and last longer.
There's a dark side too, and that shouldn't be forgotten. There are plenty of women in relationships with men who take a pill and then make unreasonable demands. The men get this magic new ability, and the women feel like they are being used as a prop.
How Viagra works is simple and it is very widely effective, on a physical level. However, each user brings their own experience, interests, passions, and relationships. So it's a multifaceted pill, just as romance has many faces.
