Is this watching from a distance while you do yourself, watching close while she does you (manually), or does she get distracted during the deed the moment you start the O face?
If the first one, sure it might be reasonable to pay a lot of attention to that when you are not part of it. If either of the other two, then she is strange. Allowing herself to be that distracted even when she is involved in the activity is weird.
Also, noisy vibrators? I say the noisier the better, helps to drown out the slop-slop-slop sound. :twisted:
