My last three GF's have been non swallowers, but I finally figured it out. guilt is the key, i just make them feel like sh!t for not swallowing and say things like you are selfish not to do this one little thing for me after all the times i've eaten you out, or you would if you loved me

, or if you really think i'm that gross then don't even do it at all. Acting like it is an insult to you personaly and really hurts your feelings...guilt, guilt and more guilt and throw in a little manipulation and you have her swallowing in no time.
I've turned 3 non-swallowers into swallowers and i am d@mn proud of it.
