I perusing some research and got sucked into some Googling... And I found a few articles that made me - as a circumcised male - think about his life:
Effect of neonatal circumcision on pain response during subsequent routine vaccination. - PubMed - NCBI
http://www.mensstudies.info/OJS/index.php/IJMH/article/view/614
How Male Circumcision Harms Women
Male Circumcision: Pain, Trauma and Psychosexual Sequelae
I hope you find them interesting too - and do add any related research that interests you :)
