I agree with Ruby - talking to him about it and sharing it with him would be a good way to go, so that the two of you can talk about it.
Try not to get into the whole "what she's got that I haven't" debate, though - that can quickly get petty. I would advise the two of you to work on what special things you have got in your relationship.
