I am baby sitting my friends crested gecko. It's a male and he is about the length of an index finger, and the width of a thumb. (No tail)

My 7 month old female gecko is about as long as a index finger as well but with a tail. She is as wide as a pinky

I let them crawl around on my bed and i noticed the male was being really aggressive towards my girl. He was pushing his nose into her belly area.
He leaped on her and bit her, my girl scattered away fast as the fat male slowly crawled after her.

I am just wondering if this is mating? or my girl is just to small to be with this male, or my female is actually a male.

I am scared if it is mating that my girls tail will fall off from the male biting.

it sounds like they're both to small to be mating, maybe the male is just really hungry, or unusually aggresive. Either way, I'd make sure that they are always separated and in different cages.

Yeah they are both separated. How big do they have to be to be mating? Or how old?

4.1 snakes, 4.3.2 crested geckos, 0.1 gargoyle gecko, 0.0.2 red-eyed tree frogs, 2.0 devon rex cats, 1.0 betta, 0.1 sun conure, 1.0 lovebird

These sizes are the appropriate sized (I think a female should be a bit larger though) to consider breeding crested geckos.
This is important as a guideline as the female needs to have some size to maintain her weight during the egg laying process.

However, cresteds can breed much smaller than this. The size of the two crested you mention is about the size they start showing signs of being a male and a female.... and, they know what they are way before the signs start showing.
So, were they breeding? I don't think they actually went through the act but it is apparent that one of them was chasing the other.
You mention that you crested is a female but at that size, can you tell for sure? What you might have experienced is one male gecko showing dominance over another male gecko. Or, as you pointed out, you might have just watched one 'frisky' male making a pass at a young female that that was saying 'get lost!'.

Ha, I figured as much. I always thought they could breed at close to a 8-11 months old, then again I am still quite a newbie with cresties.

I guess I'll find out how these two lovers pan out in the next year or so
