In psychoanalysis there is the concept of transference where the person's intense feelings about another person are transferred to the analyst. One common form of this is erotic attraction and there all too many male analysts willing to use this phenomenon to exploit attractive female clients. (Though not all transference is erotic. For instance hostility can manifest instead)

I believe some degree of transference often occurs in subs who see a domme regularly and exclusively for an extended period. Speaking personally there were 2 dommes whom I initially regarded as only mildly attractive but after several sessions found much more attractive and in both instances realized I was experiencing transference.
