There is really nothing you can do about this phenomenon, sorry. If your girlfriend is sensitive to this she may be willing to go the extra mile to make sure you get yours (oral, anal, hand job). In my opinion it is unlikely that this would happen with another partner-so if it bothers you that much it might be time to move on. If your willing to stick it out though, it could get better on its own, by having frequent sex your bodys will essentially learn each other and this may naturally work itself out.
