Im a christian can you finger yourself?

yes. as long as u dont tell anyone.

Actually there is no 'rule' against masturbation. The Bible says nothing on the subject, nor did Paul, nor did Jesus himself. So why you are afraid, I simpy do not know. Maybe it's because of some in the Church who themselves are sexually repressed and pass on that prejudice to others. Read the Song of Songs in the Bible and see how God blesses his gift of sex - used in the right context

Of course! I am 12 and the Bible says to treat your body like a temple, therefore pleasure of the body by one's self is alowed but leave the rest to after marraige to whom you'll spend your life with.
