Demisexuality is a sexual orientation in which a person feels sexually attracted to someone only after they have developed a close emotional bond with them. It is a term used to describe individuals who do not experience primary sexual attraction, which is based on immediately observable characteristics such as appearance or smell and is experienced immediately after a first encounter. Instead, demisexuals can only experience secondary sexual attraction, which occurs after the development of an emotional bond. The prefix "demi" means half, which can refer to being halfway between sexual and asexual.

It is important to note that demisexuality is not the same as asexuality, which is the lack of sexual attraction to others. Demisexuals can experience sexual attraction, but only after forming a strong emotional connection with someone. Demisexuality is also not the same as being celibate or waiting until marriage to have sex.

Demisexuality is a relatively new term and is not widely known or understood. However, it is a valid sexual orientation like any other and applies to people across the world. It is important to respect and understand different sexual orientations and identities, including demisexuality.
