Pushed forward, or pulled back? Namely when on your side? When you get into position and prepare to relax, does it look like you just thrust forward into someone, or pulled back coming out? Sorry all the explanation, but I asked this a while back, and don't think I conveyed my question good enough.
I don't think position matters too much. I always start a session in the same position I sleep in, on my side with one leg straight and the other bent resting on top of my body pillow (dakimakura). Butt out slightly so my erection doesn't touch the pillow. When things get going I change positions frequently.
But the main thing I want to know is if your hips are forward, or back most of the time.
Back, most of the time. It's easier to relax those muscles with your hips bent slightly.
Would say back works best for me. Usually start out on my back and relax enjoying each and every tingle and spasm of pleasure! Seems easier to relax and control muscles in that position!
