The authors focus on the influence of participants' having or not having a steady partner when reference to cybersex use. Participants were 1,239 young, Spanish individuals who completed the Internet Sex Screening Test. Results showed the influence of being in a relationship on certain consumption dimensions of cybersex; the influence was found to be greater in men than in women. In general, cybersex activity was higher for single participants, although it was also significant for participants with a steady partner. The authors' findings facilitate the comprehension of the effect of new technologies in intimate human relationships.
