If you have a crush on your cousin and you want to express your feelings go ahead. Also if you are on a relationship with your cousin feel free to write (type) down how they make you feel. I have a huge crush on my cousin. Every time o see her I feel my world is complete. My heart beat raises and all I can think about is her. On family reunions I mostly concentrate on her. When we are alone I wanna tell her how I feel but I'm afraid it will ruin our great cousin friendship. When I'm around her I feel confused but in a good way.i wish she knew how I feel about her.
