God, in His infinite wisdom, made these boys BOYS. He also made them attracted to girls, a lot. At least, once they start noticing that girls smell good and look pretty, too. Reminds me of that last scene in The Jungle Book when Mowgli spots the little village girl and is mesmerized to the point of carrying her water jug back to the village for her.
We're big believers in preparing our boys for the road, rather than running ahead of them attempting to prepare the road for our boys. And the road they need to be prepared for is fraught with temptations, isn't it?
Equip, teach, inform, live, and have the conversations. The tough ones. The ones that make you uncomfortable and maybe even a little sad because the end of their innocence is in sight. Prepare them for the road.
And remember their frames. They are finite, human, weak, sinners, just like I am and you are. So continue to have those conversations, asking them questions that address the "elephants" in the room and the deepest recesses of their hearts. Help them to understand their own frames, their own failures, their own need for the perfection of Christ.
Pray for them, mama. They need the Holy Spirit more than ever. And then shower abundant grace and mercy all over them because in it all, you are remembering their frames.
