Why is sexual tension important in a relationship? How can you keep it alive in YOUR relationship?

Sexual tension is what differentiates a romantic relationship from a friendship. There is no sexual tension in a true friendship; and if that changes, then the dynamic of the friendship has been lost.

Of course, it is quite possible for people who began as friends to find themselves falling in love and to consider a sexual relationship. This is fine if those feelings are mutual, but it will destroy the friendship if they are not (quite a few Hollywood films use this dynamic as the basis for a plot).

But in a sexual relationship, sexual tension is essential. You need to feel excited by and about each other, because this is the driving force for the sexual relationship that is a vital part of your relationship.
