First off, don't put toothpaste on it, it doesn't help, it will only damage your skin (particularily you have sensitive skin).
If you must get rid of it (it's best to leave them however obviously this isn't always feasible) make sure you do it in a clean manner, i.e don't use grubby fingernails. There's always the danger of infection and scarring.
And to the people saying "wash more" sadly this is not the cure. In fact, overly washing can make things worse. Sadly in many cases it's not being "dirty" that causes these things - a stigma which acne sufferers will quite often be frustrated by.
