Information about Sexual Network
A sexual network is a social network that is defined by the sexual relationships within a set of individuals.
Recent epidemiological studies (see below) have investigated sexual networks, and discovered that the statistical properties of sexual networks are crucial to the spread of venereal disease (VD). Sub-graphs, both large and small, can be defined within the overall sexual network graph; for example, people who frequent particular bars or clubs, belong to a particular ethnic group or take part in a particular type of sexual activity, or are part of a particular outbreak of a VD. In particular, assortative mixing between people with large numbers of sexual partners seems to be an important factor in the spread of VD.
In a surprising result, mathematical models predict that the sexual network graph for the entire human race appears to have a single giant component that indirectly links almost all people who have had more than one sexual partner, and a great many of those who have had only one sexual partner (if their one sexual partner was themselves part of the giant component). Most people who are not part of the giant component are either virgins, or couples who have never had sex with anyone except each other.
For serious epidemiological work, the time sequence of sexual contacts is important.
Studies & Discoveries in Sexual Networking
Like other forms of social networks, sexual networks can be formally studied using the mathematics of graph theory.Recent epidemiological studies (see below) have investigated sexual networks, and discovered that the statistical properties of sexual networks are crucial to the spread of venereal disease (VD). Sub-graphs, both large and small, can be defined within the overall sexual network graph; for example, people who frequent particular bars or clubs, belong to a particular ethnic group or take part in a particular type of sexual activity, or are part of a particular outbreak of a VD.

Virginity is a term used as an expression of purity. In its most common context, it is a concept that refers to the state of a person never having engaged in sexual intercourse. A person who still has his or her virginity can accordingly be described as being a virgin.
