I came across this story in the NY Post where parents are now paying experts to have the sex talk with their kids.  And here's an actual job posting I found!

Now I can only imagine have the 'birds & bees' talk with your kids would be uncomfortable.  My parents never had 'the talk' with me.  I turned out alright, I think?  lol.  Well, my daughters are 5 & 1.  I'm still years away from even having to think about addressing that topic with them.

Does not doing it, or does paying someone to do it make you a bad parent?  In my opinion, no.  But I can see how some might think so.
