Demiacespike is an orientation on the asexual spectrum. It is defined as someone who usually feels no sexual attraction, but occasionally has rare, sudden, and intense spikes of sexual attraction to people they have a bond with for a short amount of time, before returning, just as suddenly, to one's normal amounts of asexuality. It may be considered a combination of demisexual and acespike. It is different from demisexualspike.
Demiacespike can be a sexual orientation on its own or can combined with other orientations. For example, one could be demiacespike and omnisexual, meaning that when one does experience sexual attraction it's towards people of all genders.
The romantic counterpart to demiacespike is demiarospike. Being both demiacespike and demiarospike makes someone demiaroacespike.
