I was wondering one day about a week ago... How the heck do worms reproduce?

So... I did what I always do when I have an unanswered question, I did some research... and what I found is WILD

Worms are hermaphrodites, meaning they have both male and female parts 

In order for worms to reproduce, they have to mate with another worm, swapping sperm to fertilize eggs... some species even asexually reproduce, meaning they do it all themselves, no sperm swapping needed 

Yeah... they are both male and female, which is so wild to me in itself 

What do YOU think about this? Did you already have the knowledge of worm reproduction?
