Abstract
In a study designed to investigate the role of conditioning starting before age 18 on adult sexual behavior and urges, retrospective data were provided by 841 men using an anonymous computerized survey. Participants were recruited from populations including college students, 12-step meetings, and the general population in the mid-Atlantic United States. Using objects inserted into their rectums or urethras during masturbation before age 18 increased by 15.5 fold and 11.4 fold, respectively, the likelihood that they would use objects similarly after age 18. Using an inserted object during masturbation also increased the likelihood of experiencing urges to use objects in relation to the individual's own genitals and/or anus. And, using an inserted object during masturbation increased the likelihood of experiencing urges to use objects in relation to the partner's genitals and/or anus.
