I don’t have kids so I dunno if it’s still happening, but my dad had a brief and very awkward conversation with me to tell me that if I had sex to make sure to use a condom but if I ever did get a girl pregnant I could always tell him and it’d be OK, we’d figure it out, etc. Nothing fancy or anything; just the essentials to make sure I wasn’t a dumbass about sex.
