The experience of being in love involves a longing for union with the
other, where an important part of this longing is sexual desire. But w
hat is the relation between being in love and sexual desire? To answer
this it must first be seen that the expression 'in love' normally ref
ers to a personal relationship. This is because to be 'in love' is to
want to be loved back. This much would be predicted by equity and soci
al exchange theories of interpersonal attraction. Findings suggest how
ever that love differs fundamentally from liking and, consequently, di
stinct approaches to the theory of love have been developed. A phenome
nological theory is then put forward which suggests that the experienc
e of being in love involves a complex of desires for reciprocal vulner
ability in order to care and be cared for. Sexual desire is then seen
to involve the physical expression of these desires in the form of des
ires for mutual baring in order to caress and be caressed. Unlike love
, however, sexual desire need not refer to the other person's desires.
This is supported by the existence of sexual desires like fetishism.
It is concluded that other desires which often appear in instances of
being in love are not basic to the experience of being in love.
