TB, You say...

"the church teaches that you should not have sex before you are married"
And yet the bible tells us that LOT, the only honourable dude living in Sodom & Gomorah, was busy banging both his daughters immediately after the cities got levelled.

"the church teaches that you should only have sex with your partner"
SO WRONG. In the Bible we have approved sexual relations between Man+Wife+Concubines, Man+Wife+Other Wives, Male Soldiers and their Female Prisoners of War, Rapist and his Victim. (She is forced to marry him) MAN and Wife's Slaves.

"the church teaches that if you are pregnant, you should keep the baby"
WRONG In Numbers 5:11-28 gives a priestly formula designed to induce an abortion in any unfaithful wife.

"what age is it OK for your daughter to have sex?"
Rebekah was 3 when she was chosen to be Isaac's wife. Personally I think that's a bit young, but who am I to argue with the inerrant word of God!
