Unless it can't be defined as a single thing, in which case the set 
cannot be considered reflexive.   If something is described as A or B it 
can't be claimed to be A.   If something is both A and B, it can't be 
called only A.   hasSameSexAs could reasonably defined as gender 
identity (developmental), gender role (social/legal status), XX vs. XY 
chromosomes, current genitalia, birth genitalia, hermaphrodite, etc. and 
the reflexive subsets over a population could all be different.
