There were no statistically significant differences on general sexual satisfaction, pain during vaginal penetration, desire, vaginal orgasm.
Studies have shown a reduced risk of human papillomavirus, genital ulcers, herpes simplex virus type 2, syphilis, bacterial vaginosis, and T vaginalis in women whose partners are circumcised.
Conclusion: The highest-quality studies suggest that medical male circumcision has no adverse effect on sexual function, sensitivity, sexual sensation, or satisfaction.
Morris' systematic review carried out in Australia [23] on early MC, with a total of 40,473 men, showed that medical circumcision (MC) does not adversely affect sexual function, sensitivity or pleasure.
A 2016 study confirmed this, finding that men who were circumcised experienced the same level of sexual pleasure as men who were not.
Circumcised men reported increased penile sensitivity and enhanced ease of reaching orgasm. These data indicate that integration of male circumcision into programs to reduce HIV risk is unlikely to adversely effect male sexual function.
Adult circumcision appears to result in worsened erectile function (p = 0.01), decreased penile sensitivity (p = 0.08), no change in sexual activity (p = 0.22) and improved satisfaction (p = 0.04). Of the men 50% reported benefits and 38% reported harm.
Three months after their adult circumcision surgeries, the men were evaluated in the same exact way, and Senkul found an interesting trend – almost all of the men had taken much longer to ejaculate during sex following a circumcision.
Results: There were no significant differences in sexual drive, erection, ejaculation, and ejaculation latency time between circumcised and uncircumcised men. Masturbatory pleasure decreased after circumcision in 48% of the respondents, while 8% reported increased pleasure.
The NMC group included 72 patients (29.0%) who were circumcised during the newborn period; the non-NMC group included 176 patients (71.0%) who were circumcised after the newborn period. There was no significant difference in height, weight, and second to fourth digit ratio between both groups (Table 3).
The paper finds evidence that circumcised men don't have any less sensitivity in their penises than men with intact foreskins.
