So you were being yourself and she was into you, you didn't continue to escalate as advised above and then you remembered what David D said about C and F so you then tried to be this person that you aren't really and then she didn't like this new person you were trying to be?
She liked the real you who was relaxed and having a good time. Then you heaped pressure on yourself by trying to be someone else...
Be yourself and try to escalate and remember that women want to feel good and sometimes when we try to do stuff we read about, it may not have been intended for our situation. Well done for trying though
and keep on practicing, you're only going to get much betterRichard Trigger
Ps, touch escaltion is as advised above would have done the trick, if she is aroused and you manage to arouse her further which is a feeling women love... there is little chance she will wont to stop
