It is simple really. All you need is a kitchen and enough supplies to make a sandwich. Since you see to be able to satisfy somebody they need to be doing something. If your chick is not doing something to satisfy you then something is wrong

So you show her your kitchen, all your yummy looking sandwich topping etc. Then tell her to make you a sandwich. This is really the battle you are not aloud to lose. If you win the outcome ( As you always should) Then you can say huzzah and eat that sandwich of victory. If not.............
