My bf doesn’t make me horny anymore

Me and my bf have been together 1 year almost 2 but took a one year break and are back together and it’s been almost2 years. He used to get me in the mood very easily but lately I just haven’t felt it. I know I can get it the mood bc I have just not with him. I don’t find him unattractive I just feel like it’s boring now it’s nothing to make me excited. Any advice on what to do in this situation?
