Sexual identity refers to how one thinks of oneself in terms of attraction to the same sex or members of the other sex, based on one’s own experiences, thoughts and reactions, rather than defining oneself based on the gender or sex of one’s sexual partner(s).
This can include refusing to label oneself with a sexual identification.
