So babes, your cock is well short, this you are probably aware of, but I don’t feel like it’s brutally or useless short. A womans most sensitive areas are with in 3 possibly 4 inches inside her pussy, which means, you have enough dick to please her sensitive areas.What you will not be able to deliver is that shaft sliding feeling that your girlfriend would rather get for your fingers, hehe. Your girth isn’t great nor is it terrible, a little pussy stretching should happen, I wouldn’t consider you skinny, you have some average girth. Your head is okay still not amazing girth, you will really need to grind this little cock against her pussy hard, and you should be able to get her off, get that engine warmed up with a bunch of foreplay first. Good luck!
