(maybe NSFW) Can you help me with my first kiss?

I’ve never been kissed before, nor have I ever kissed. I’ve talked to a friend, and he said he had a surprise for me at lunch, and for a fact I know it’s a kiss because we’re so close, we’re almost a couple. And when he said it, he said it in like a mysterious, sexy kind of way.

Can you walk me through some techniques on what to expect, and not expect?
