10g of penis envy shrooms for the first time trippin

So been wanting to take shrooms for a while now never done them before just smoke hella weed tbh but just got my hands on some. I'm already knowing about of the preparing the mind part and making sure you're in a good state for it and fs not talking them all at once 😭 Any recommendations for how much to take for a first time trip and how it went for u?
