First time getting high? What to expect?

So I've been best friends with this guy for about 2 years now & he's such a wonderful person. He knows how to make me happy & always cheers me up when something is upsetting me. He recently told me that he has been smoking weed for a few years now and I never knew this about him. We hang out often and he has never done it in my presence. Lately I've been going through some personal issues and have been exploring a lot of new things that I wouldn't ordinarily consider. I promised him that I would get high with him for the first time on my birthday (just a few days away) and I want to know what to expect and how I can ensure a good experience :) Thanks guys!
