Oh wow! A fifth grade love tale.

100% AGREE ON WHAT SHAWN SAID ^

That is why watching porn can be helpful

I know that you maybe nervous, but there is really nothing to be scared of, but I will give you one advice that really helped me out. It's that never stick it in the vagina, they all like it in the butt.

It is OK to be nervous about your first time. What will make you feel better is if you talk to your girlfriend's father first. Tell them that you two have decided to start having sex but you are concerned you will not be able to please her since it is your first time. Ask him for any tips or pointers on how to do this properly.
