Help I feel like his friend not his fiancé!!!!

I need help me and my current fiancé have been together since 2011 but I don’t feel the romance anymore. I know he loves me and I love him but we’re so comfortable with each other that it feels like we’re just really really good friends. I just I don’t like it and I’m trying to figure out how to get the romance back into our relationship. We don’t really hold hands we don’t really kiss we don’t hug we don’t really have sex. We’re just really comfortable with each other and I don’t want to let this continue and it gets worse. I’m not happy but I don’t know how to tell him I’m not happy without hurting his feelings. I’m scared that if things continue to go this way I’m gonna wake up one day in my 40s with regret because I spent my life in a romanceless relationship.

Update: I talked to him like everyone said (without saying unhappy) and it turns out he was feeling the same way. We both agreed to work on bringing Intimacy and affection back into our relationship. I know that it’s not gonna happen overnight but I glad at least we’re both willing to work on it . I appreciate the help because I have really bad anxiety when it comes to the people I care about and I never want to make them feel bad but I really needed this push. Thank you 😊
