<human>: Tell me your most embarrassing, insightful, awkward stories of when you had "The Talk", either as a child receiving the talk or as an adult giving the talk.

I hope to learn from your experiences in hopes that when I give the talk to my 13 y/o son I can avoid your previous mistakes and also to take into consideration any insights you can give me.

More:  My son and I are very open and he talks to me on a regular basis about all sorts of stuff I would not have talked to my parents about: girls, friendship issues, school dealings, etc..  So I know it won't be completely awkward, but I don't know what details to discuss having never received the talk myself as a child.  Help me reddit!

Could you distill the essence of the text into 1-3 sentences?
<bot>: As a dad, I'm about to give the talk to my 13 y/o son.  Guide me by telling me your "talk" stories or what i should/shouldn't say.
