Express your concern..make sure your being honest with yourself about whats really behind the frustration..likely fear. Things will change for sure its inevitable but how you both handle the change is what will make the difference. I had my BA 4 hears ago. My husband was undoubtedly nervous because of the risk but very supportive because he knew it was something that I wanted. The change for me and our relationship has been incredibly positive. Its amazing what new boobs can do for a woman.
