Contraception help

Stephanie
I'm wanting to go on to 'the pill' as my boyfriend and I have become active and we want to be as safe as possible. All my friends are on it so I've asked them these sorts of questions and things too. But I'm still not 100% sure about it. 
During sex can he ejaculate inside of me and I wouldn't get pregnant as I was on the pill? Or do I have to use the pull out method while  using this form of contraception just to be sure?
