Am I missing something?

I am seriously perplexed by all of the women I've been describe "pulling or twinge in my uterus" "pain in my left ovary" etc. Am I supposed to be able to feel my uterus and ovaries?!? Someone please explain to me what I'm missing here- I have no idea what my uterus or ovaries feel like or even exactly where they are (obviously I know generally where they would be but I can't feel them..that's like saying I can feel my gallbladder- sure, I know it's supposedly there but I can't feel it). Help?
