This is truly a brilliant interactive resource that allows the user to view specific muscle groups within the pelvis and locate the larger nerves in the pelvis, including the pudendal nerve. Almost like building a 3d version at your own pace (yes, you can unbuild it!). Be sure to scroll the smiley face up and down the right side bar. Link to resource
