Lupe if you don't know the answer to birth control and being fingered, I don't think you are ready to sexual activity also if his hands are not washed properly you can catch a very serious infection that can lead to many other future serious problems.
Please make sure that you become well informed on sex and birth control first before you begin being sexually active.
Birth control helps prevent pregnancy, and intercourse is needed for that. You are fine if you are only fooling around. If you plan on having sex soon though, I would suggest you get birth control now so it can become effective. (It takes up to 3 months before it's effective)
Now why would you think that you would need that?
