Changes

Laumann et al. (1997) reported that men who lack a foreskin "engage in a somewhat more elaborated set of sexual practices than do men who are not [[circumcised]]. For each of the practices examined, lifetime experience of various forms of oral and anal sex and [[masturbation]] frequency in the past year, circumcised men engaged in these behaviors at greater rates. The difference between circumcised men was greatest for [[masturbation]] - — ironically, a practice that [[circumcision ]] was once thought to limit. A total of 47% of circumcised men reported masturbating at least once a month vs 34% for their [[uncircumcised]] peers."<ref name="laumann1997>{{REFjournal

Cold & Taylor (1999) commented, "The increased frequency of [[masturbation]], anal intercourse and fellatio reported by [[circumcised ]] men in the [[United States of America| USA ]] may possibly be due to the sensory imbalance caused by [[circumcision]]. Clearly, [[amputation]] of the prepuce causes changes in sexual behaviour in human males and females."<ref name="cold-taylor1999" />

Frisch et al. (2011) surveyed the sexual function and behavior of a large group of [[intact ]] and [[circumcised ]] men in [[Denmark]]. They reported that "circumcised men were more likely (38%) than [[uncircumcised]] men (28%) to report ≥10 sex partners."<ref name="frisch lindholm groenbaek 2011">{{FrischM LindholmM GroenbaekM 2011}}</ref>
