ABSTRACT
How often do people have sex and what do they actually do when they have sex? In the context of AIDS and STD, these issues are of great importance, since people's sexual behaviour is one of the most important determinants of the AIDS epidemic's further development. In this chapter we shall answer these questions as they pertain to people in various countries in Europe and explore differences between countries as well as identify patterns these countries have in common. The focus of this chapter is not on risk behaviour, but on the way sexuality in general is structured by social and demographic factors such as gender, age, and educational level. These insights are essential if one wants to promote the adoption of safer sexual practices effectively.
