Try to remember though her O isn't your responsibility. It isn't necessary for her to have an intense O all the time. Sometimes too YOU will have no control over the intensity or...whether she has one. If she has one quickly and it's small, that's fine. Just go with it. Sometimes there isn't any controlling it. Some days you may fire her right off....some days it may take 20 minutes or longer LOL.
Try to remember the O isn't the important thing...the connection is. But it's all fun isn't it?
