How to do doggy sytle.?

I have only had with my boyfriend and we have had plenty of times but its always me on top or him on top. I am always open to new positions and he suggested doggy sytle. I am still new to this whole thing still. I understand that Im gonna have to bend over which Im not exactly sure what you mean to "bend over" though. I dont want to feel or look stupid when we try this. He hasnt tried it either but hes more confident then I am. Help please!
