How do I act "normal" after coming out to best friend?

I just told my first friend who is actually a good friend of mine that I'm gay. The other people I came out to were like guinea pigs, which I feel ashamed about now.
I was wondering how do I get back to talking normally with him? My friend received it pretty well. But he told me he's still adjusting to it. He said he researched about gays after I came out to him. Then he told me I could just be curious. Then we had this awkward conversation about who I liked (I actually like him so I told him somebody else) and just basically homosexuality.
OK quedtion time! I guess what I'm asking is how do I try not to take some things he says about gay people in the wrong way. I know he's just wondering. And when my friend feels all his questions have been answered how will I get used to it. I think I told him before I was completely comfortable with who I am. Also, how do I make jokes out of it? So it won't seem so awkward.
