THE DEMISEXUALITY OF THE 4TH LINE

Human Design is the Science of Differentiation. As we move towards the 9-centered era, the mutation in the solar plexus center is taking place on an ongoing basis and is deeply affecting how we process and experience emotions. And that is changing a wide spectrum of human behavior, from connecting to relating, to bonding and mating, to sensuality and sexuality, just to mention some.

Demisexuality is an emerging term, created in 2006, to designate a sexual orientation placed generally on the asexuality spectrum. Demisexuality refers to how an individual experiences sexual attraction; it does not describe a choice or an action, but describes a feeling instead. A demisexual is a person that feels sexual attraction only to people with whom they have an emotional bond. Whatever that emotional bond is, demisexuals only feel sexual attraction to those with whom they have developed a certain level of emotional intimacy. That threshold will be different for each demisexual, but it has to be there. Because of the individualized nature of emotional bonds, they could take any length of time to develop. It is important to note that demisexuals do not always feel sexual attraction to people with whom they have this type of bond. It’s just that the bond has to be there for sexual attraction to occur at all. Some demisexuals have a gender preference, while others don’t. Other demisexuals find that the sexual attraction becomes stronger or only appears when they are feeling particularly connected to the person.

If you have a 4th line in your human design profile, you are an opportunist; a social being that has to be presented to people and only after developing a bond and being known by others, to be able to start exteriorizing and influencing your network. Friendship before intimacy is a motto for a 4th line; in fact, strangers can be very dangerous for these people. Whether in terms of the bonding strategy (4th line personality) or the sexuality (4th line design), the mechanics is: confidant or not. Confidant is a person you trust and share your feelings and secrets with. In a play, the confidant is a type of secondary character in the story, often a friend or authority figure, whose role is to listen to the protagonist’s secrets, examine their character, and advise them on their actions. To have a well established bond is imperative to be a confidant to someone.

Obviously that doesn’t mean that every 4th line being is a demisexual; we are talking about the Science of Differentiation after all. But a 4 will experience in their trajectory, in a higher or lower degree, with more or less intensity, that need for a bond before intimacy can be developed.
