Just moved to San Francisco, looking for stuff to do and hidden wonders to see!

I just moved down to this wonderful city. It's beautiful and I've enjoyed wandering around seeing the city. However, I don't have much direction in finding really fun places/things to do in the city. So much is going on I don't know where to start! I'm wondering what are r/sanfrancisco's favorite haunts and some events to check out over the next few months. I want to know about the gems that people don't know that much about when the first come to the city(I know about the touristy stuff). I have a wide variety interests including art, science, music, cooking, dancing, food and drink(I love everything, lame I know!). As a result, I'm up for almost anything(preferably not things that rely on dishing out huge sums of cash though). I am also into looking at more adult fun(interesting parties, nude spelling bees[fun!] etc.) I don't want to spend my weekends going to movie theatres(I am Canadian, sorry, theaters), unfortunate restaurants or sitting at home when I know that there is so much that San Francisco has to offer!

Thanks in advance!

TL;DR Just moved here. I want to know about the non-touristy things in San Francisco that are awesome!

EDIT: You guys are awesome! So much to do, some much see!
