how much for first time?

well my friend just came up to me with the idea to do shrooms, he just wants to do 2 grams and he makes it sound like that'll be good, i want to go for 4 maybe 5 depending. also since this is are first time with shrooms he does'nt want much so he can make sure i'm alright but i think we should just do both like 4 grams and chill but he thinks thats gonna be nuts. also what should we do to chill i heard a movie makes you focus less on your trip but i dunno what to do to really chill, we're gonna stay inside cuase it's freezing out so maybe draw and write a story.

 

Isn't 5 grams considered a hero trip? Anyways me and my friend both took 2g each on our first time tripping on them and we were pretty out of it.
