Not being able to make a noise may be holding me back.

Someone posted recently that this journey is like climbing a mountain in the fog. I think that's the best analogy I've read. I'm finding new sensations after nearly every session and am enjoying MMOs with and without my Helix. Thing is when I'm having orgasms I just want to moan and shout to release the energy but I can't, what with the kids in the next room, they're old enough to know what is going on. I've read about how making noises helps on the path to the super O and am wondering if biting my pillow is somehow slowing my progress. It seems the natural thing to do when you're in the middle of a blood vessel bursting dry O is to holler like a banshee...!
