I don’t know if it was a birds and bees sit down or not. The OP didn’t state how the conversation got started…or who started it. Either way, I don’t see how that makes any significant distinction. Our children’s consciences are formed every day, this should be something that is discussed even outside the sit-down-birds-bees-convo. The OP’s own heart is now at odds with what his parents have taught him. I don’t see how this is inappropriate for him to have discussed with them. They have clearly exposed this harmful message to him, now he has questions. He did not pull their cafeteria approach out of thin air – they told him. Now he must try to reconcile this from the ones who are supposed to be shaping his conscience. I should hope that a conversation would be in order given these facts.
