I don't blame you for feeling that way as its a very natural
thing for boys, and perhaps you havbe a high-sex drive,
i would advise that you would keep yourselve busy for example help
up in the cleaning of your house? just try not to think about
sex-related stuff.
If one day you are too much, try explaining to your galfriend, i am
sure she will be understand, but ithere no excuse to use after all
its about your self-control.
