Sanssexual refers to someone whose attraction changes randomly. Their orientation is very fluid and there is no trend line in the attraction. As such, sanssexual individuals may not feel compelled to seek out a sexual relationship, or they may prefer a fluitic relationship/wavership. However, this is not true of all sanssexuals, and some will seek out sexual relationships regardless of whatever attraction they may feel.
