More About Agnosexual
An individual that identifies as agnosexual has not decided upon or does not specifically identify with, any sexual orientation. Typically, agnosexuals tend to identify as agnosexual rather than bisexual or any variation thereof because identifying with a sexual orientation such as bisexuality brings with it preconceived notions of those that identify with that particular sexual orientation.
