Should I tell my long distance boyfriend I kissed someone else?

Anonymous
I'm in a long distance relationship since the start of summer. I live in Scotland, he lives in Australia.

The other night however, I was out and had a quite a bit to drink, one of my guy friends who likes me kissed me, I kissed him back however then I realized what I'm doing, pulled away and told him I have a boyfriend.

I know myself that the kiss meant absolutely nothing and that my boyfriend is the one I love. It was drunken mistake - I guess I just missed the physical aspect of being close to a guy.

He's coming to visit at Christmastime, should I tell him face to face then, or should I tell him now? or not tell him at all?
