She thinks I am her mate.

Hello, please forgive me for bothering you! I saved a female pigeon a couple of months ago. Since then we've bonded, but it seem she thinks I am her mate (she gently pecks me with her beak on my head, face and arms; she ''presents'' herself from time to time, etc.). Will this be a problem in the future? I leave her alone for several hours a day when I'm working, but I spend the rest of the day with her. I do not keep her in a cage! I let her do whatever she pleases in the apartment (I clean constantly after her). I leave a lot of food (for racing pigeons); water for bathing and drinking; grit (several types of it); minerals and vitamins. I really want to give her an amazing life! Could you please give me some advice, I beg of you! I am not a native english speaker, so please excuse any mistakes you may encounter. Thank you in advance!
