Felt attached to my boyfriend's nosebleed tissue

Would've placed this in "Relationships" but this topic is, unique. What makes this more strange is that we just started dating but we feel close. Anyway, I finally flushed my bf's bloody nose tissue. But, I was hesitant to get rid of it for weeks. He has allergies and while we were being intimate he had a nosebleed and left his tissue. I took it to my room just to "keep it safe" in my trashcan. I wanted to throw it away eventually but, it's a part of him. I even opened it and observed it, just once before tossing it and again before flushing. I took note of how it turned brown from time. It was a reminder of that evening and I never had anyone else's blood before. I felt closer to him just because I didn't find it gross at all. I only cared about him being ok. I flushed it to keep it from being in a landfill which bugged me to imagine for some reason. Burying it would've been too confirmative of my weirdness so I avoided that. I'm sure it's not normal haha..
