Cortés-González et al. studied 19 female partners of men scheduled for circumcision. They reported a significant reduction in vaginal lubrication following circumcision, from 78% to 63%, but found no statistically significant differences in "general sexual satisfaction, pain during vaginal penetration, desire, [or] vaginal orgasm".[39]
Kigozi et al. reported on a prospective study of 455 female partners of men circumcised as part of a randomised trial. 39.8% reported improved sexual satisfaction following circumcision, 57.3% reported no change, and 2.9% reported reduced sexual satisfaction after their partners were circumcised.[40]
Williamson et al. (1988) studied randomly selected young mothers in Iowa, where most men are circumcised, and found that 76% would prefer a circumcised penis for achieving sexual arousal through viewing it.[41] Wildman and Wildman (1976) surveyed 55 young women in Georgia, US, reporting that 47 (89%) of respondents preferred the circumcised penis (the remainder preferred the uncircumcised penis).[42] Bailey et al. report that there is a preference by women for circumcised men, mentioning that the circumcised penis enters a woman more easily and is less likely to cause injury to the vagina.[43][verification needed]
Frisch et al. (2011) studied participants in a Danish national health survey, and found that male circumcision was associated "with a range of frequent sexual difficulties in women, notably orgasm difficulties, dyspareunia and a sense of incomplete sexual needs fulfilment."[33]
