Umm ok. All I want is to be able to put my hand In and pet her a little w/o her biting me
Geckos of many species are generally not big fans of being pet. Many can learn to tolerate handling very well, but petting them on the head or sides, back or tail often results in defensiveness on their part. These are vulnerability points for them - they can't see you, and in nature, would often be attacked by a predator in one of these locations.
This is why it's often recommended when handling to simply scoop them up from underneath and allow them to walk/go where they want on you without you getting your hands in their face or all over them. Even my most docile geckos will start breathing quicker if I touch them on the back or head...and these are geckos I've had and worked with for years.
I also have other geckos who tolerate being held just fine...but if my fingers come anywhere near their face/heads, they get very defensive and will attempt to bite.
Handling should always be tailored to what your gecko will tolerate and what works best for them, not you. In your case, your gecko sees you as food or possibly a stressor when you have your hands that close to her head. Scoop her up from the side and allow her to lick you, if she chooses, on her terms.
