Is it normal to want to have sex under the christmas tree?

When I was first married on November 20th, our main activity was sex for about two weeks with occasional rest periods in between. We did it in bed, under the bed, on the floor, in the easy chair, on the kitchen counter and everywhere except on the roof. When Christmas came I put up a tree with full decorations and one evening during our usual activities, I glanced over at the beautiful tree and was filled with the desire to have sex under it with my wife looking up into the tinsel and angel hair.

Whenever I see a nice decorated Christmas tree now, after all those years, I have the strangest urge to grab my beautiful princess and do it under the tree just as I dreamed years ago. Is it normal or was I just bitten by Rudolph, The Red Nosed Reindeer when I was sneaking down stairs early to peek on Christmas morning?
