First part is about your body care. For now on I want you to use my product. From soap to perfume I want you to match my smell perfectly. I don’t want any other smell ruining mine. When we'll go out together, instinctively everybody will know I own you when they’ll be near us and smell me through you.
When you’ll be alone, you will just feel constantly humiliated knowing everybody know this is not the smell of a man.
You are lucky that this new trend of man playing with gender are a thing right now. You will be able to use it when you will explain to your friend why you smell like your girlfriend.
