Previous research indicates that adults believe that sexual desire and sexu
al activity play different roles in love relationships. Little research, ho
wever, has been conducted to document the presumed differences between thes
e two aspects of human sexual response. The purpose of this study was to ex
amine empirically (1) whether sexual desire and sexual activity co-occur in
dating relationships; (2) whether desire is more strongly associated than
activity with passionate love; and (3) whether desire and activity have dif
ferent implications for relationship maintenance. The results revealed that
sexual desire and sexual activity were moderately (but not significantly)
related. In addition, and as expected, only sexual desire was related to pa
ssionate love. Sexual desire also was related to relational maintenance; th
e greater the desire for the partner, the less often participants thought a
bout ending their current relationship, thought about beginning a new relat
ionship, reported being unfaithful to their partner, and felt attracted to
others.
