same here, she thought it was hilarious. So I started doing the same to her. Doesn't really have the same affect, and besides.. the only time where it might have been affective, it was also affective on me haha.Haha yah its definitely blue balls. My ex-GF did that a lot to me, purposely. We would "spent some time with eachother" and then after a while she just stopped and waited for my agony.
