Do you think this is normal during ?

I am with a girl and find it hard to get off. Basically what I do is I first bring her to orally or using my fingers and then I want to get on top of her and get off myself. But she seems to want to control the rhythm and speed when I'm on top which makes it harder for me to get off. In fact when she tries to control things I lose my pretty fast. It is like my wants to be in complete control. I cannot control it - I would if I could but it has a mind of its own and wants things the way it does. I don't know what to do. She is very wet and I did bring her to so I am not sure if I'm being selfish or not. The main issue though is I want to get off ( or my ) does and it likes just to have pretty intense .
