First, please don't misunderstand, this is a serious question, I am not some jerk trying to feed my ego.
Is it possible for a woman to become uncomfortably over-excited?
A couple of times now during oral sex on her, my girlfriend has abruptly pulled away saying "that's too much, I can't handle it". She seems to almost lose her breath then I notice her rubbing her clit while trying to calm down. Then she'll say something like 'we can't do this all the time..I can't take it...". Of course I try to stop when she says too, but have I pushed it too far? Is it possible for a woman to be uncomfortably over stimulated? is it unpleasant? How should I handle this.. I want her to be happy, not uncomfortable.
