Asenspike is an orientation on the Asensual Spectrum defined as someone who usually feels no sensual attraction, but occasionally has rare, sudden, and intense spikes of sensual attraction for a short amount of time, before returning, just as suddenly, to one's normal amounts of Asensuality.
Asenspike can be a sensual orientation on its own or can combined with other orientations. For example, one could be Asenspike and Bisensual, meaning that when one does experience sensual attraction it's towards two or more genders.
