Blah, joints are really harsh. I proposed the gravity bong for the first time because if you want to get HIGH on the first time, the gravity bong will definitely do you justice. It took me seven tries to get high for the first time. So maybe I'm being a bit...assertive. Use a bong/bubbler/vapo it will make the first time much more pleasant. And, yes, if he doesn't want to do it, don't force it.
