A demisexual is a person who does not experience sexual attraction until they form a strong emotional connection with someone, often (but not always) in a romantic relationship... When describing demisexuality as an orientation to sexuals, sexuals often mistake it as an admirable choice rather than an innate orientation. Demisexuals are not choosing to abstain; they simply lack sexual attraction until a close relationship is formed.
