Just under one-third of the population see sex as a crucial part of life.

Generally speaking, espousers have moved on from youthful anxieties and know what they like, do not like and what they are likely to do when it comes to sexual activity. Sexual activities and pleasure are intimately linked in their minds.

Cutting across all socio-economic groups, espousers of this basic attribute not only believe that they have the ability to enjoy sex, but are confident that they can adapt to change and find ways to make intimacy with their partner even better. They recognise that mutual pleasure and satisfaction is the clear path to take. As partners, they know that they need to learn from each other.

Their approach to sex is not fixed. They tend to be well informed and up to date with regards to current sexual attitudes and behaviours, which fuels their need to keep things interesting, perhaps exciting. They are willing to experiment and to explore new ways that suit their current needs, age and temperament.

Pleasure gives their life a sense of purpose. It is obviously one of the primary drivers for sexual satisfaction, but the nature and character of that pleasure can change over time. When younger, there tends to be a focus on enjoying the moment and not thinking about the future. As they grow and accumulate experiences, they may become even more experimental - based on their life perception, where they tend to believe that most things turn out all right.

Espousers tend to multi-sensuality, finding pleasure not just in sex but also public displays of their worth. The homes of espousers will tend to be as much about a confident display of their achievements as it will be an invitation to share their achievements with them.
