So, I have personally never had children so I do not know what it would feel like, but these guys do now!
This is a video of Dennis and Valerio from the Dutch show Proefkonijnen (Guinea Pigs -- turn the English subtitles on) getting electrodes strapped to their stomachs and electrified in waves to mimic the last two hours of contractions before childbirth. They both do a pretty good job coping at first but as things intensify one dude calls it quits because he's a sissy and should never be allowed to have unprotected sex again in his entire life. The other guy manages to survive the whole two hours. Obviously that first guy just doesn't have what it takes to be a woman .
Hit the jump for the video, but skip to 3:00 for the shocking to start, skip to 5:00 for the real pain to begin and for all you women who have given birth before skip to 7:00 and just smiiiiiiile.
