When talking to your son about sex this should be fairly simple. Tell him sex feels really good, until you see the end result, which was you, so wrap that shit up. Go into a long speech about how the last thing he wants is a child running around, explain how it really messed up your life. Then when he isn’t catching your drift. Tell him “You specifically are the reason I cry myself to sleep each night.” But make sure you end the conversation on a high note by then giving him a big box of condoms wrapped like a Christmas gift. When he opens it up say with a proud grin, “Go to town, boy!” But let him know the rules for engaging in sex. Say, “Look your 15, so it’s important to remember you never want to sleep with the same girl twice, when you get married you will have the same woman for the rest of your life and trust me that really sucks.” Then explain if the girl looks funny down there that’s what the condoms are for! Enjoy.
