Replying to First time smoking tips?

Well I just started dating this girl who turns out to be a little bit of a pothead. Even though ive been around marijuana in my life ive never actually smoked, which is a little weird considereing all my siblings and friends do. I think one of the reasons ive stayed away from it is my brother was on heroin and a bunch of other weird shit at one point and he was probably my only chance of smoking.

back on topic, I need tips on how to do it correctly because I dont wanna look like a diptard in front of my girlfriend.

pretty sure it was safer to ask this on newschoolers than hear answers from 30 year old moms on yahoo answers.
