For a first date, this was too much intensity. Intensity is the degree, volume, or magnitude of a thing, such as fire, emotion, weather, work, or passion. Intensity is a word sometimes associated with passion, fire, and violence. It's used when discussing the level of such things as a love affair or, perhaps, a flame. For example, the intensity of the relationship between Bergman and Bogart in Casablanca was very high.
