What I mean by sensitive is that when I move the mouse a little bit, the cursor goes a long way.
I'm using GNOME, I've had a look at the settings and there isn't anything (as far as I can see) to change the sensitivity. I thought there might have been a conf file or something like that with some changeable values?
I have Gnome in Spanish, so I don't know how is it in your language. You can adjust the sensitivity clicking in the upper right corner, in your name, "System Configuration", and then "Mouse and touchpad". There you can configure it.
