Coeosexual

Coeosexual is a sexuality on the asexual spectrum that is the opposite of demisexual. Coeosexual people can experience sexual attraction for people they have not met before, although these feelings may be fleeting, or not strong enough to warrant a relationship. Coeosexual people are prone to intense crushes on people they barely know, which can be as intense as an attraction an allosexual person would feel after developing a relationship over many years.
