Demisexual is a sexual orientation on the asexual spectrum defined as someone who does not experience sexual attraction until they have formed a deep emotional connection with someone.
The term demisexual comes from the orientation being "halfway between" sexual and asexual. Nevertheless, this term does not mean that demisexuals have an incomplete or half-sexuality, nor does it mean that sexual attraction without emotional connection is required for a complete sexuality.
Demisexual can be a sexual orientation on its own or can be combined with other orientations. For example, one could be demisexual and gay, meaning that when one does experience sexual attraction it's only towards people of the same gender.
The prefix demi- means half or partial. The prefix is also used in the word such as demigod
