Allosexual

Definitions and Usage
Allosexual (also called "zedsexual") is a term for someone who experiences attraction (particularly sexual attraction) regularly. Basically, the opposite of asexual (experiencing little to no attraction). On its own, allosexual is not a part of the LGBT+ community, but it can be combined with queer identities such as transgender, gay, bisexual, or aromantic.

Flags
Allosexuality, or sexual attraction in general, is sometimes represented by red stripes (such as in the aceflux flag) but it has no official "flag" since it is not considered a part of the LGBT+ community.
