Comsexual is a sexuality that refers to someone who experiences attraction. It is the opposite of asexual in that way, however it is different from allosexual. Allosexual is an umbrella term, and can refer to anyone, gay, straight, bi, etc, who feels sexual attraction. Comsexual, on the other hand, is a specific identity for someone who feels sexual attraction and can't/doesn't want to specify their identity any farther than that.
Comsexual falls under the umbrella of pomosexual. Pomosexuality is defined by the idea that one's orientation does not fit into any labels that currently exist, so therefore one chooses not to define one's orientation. Comsexual is a label for those who do not wish to narrow down their orientation any further than the fact that they feel attraction.
