I see what your both saying, but im a guy and generally bigger and stronger then the girl...so i just take myself away from her.
If shes touching me but not as much (or where) i want, i simply take her hands off me and turn my back on her or walk away. I may even tell her "Eh, im not feeling it, your not really selling it." or some variation letting her know its not enough.Especially if she states your not allowed to escalate...then i just go "If i cant touch, neither can you." or "Well if thats the case you dont get anymore".
Girls do love to argue, but even more then everyone else they want what they cant have...they also want to be in control. What i do is give them the options that let them think they are in control, while giving them what they think they shouldnt have. Or better yet i make them decide if they want what they cant have or control...they will always pick what they cant have.
After all i am the prize, she must earn it.
