Is it normal to store my own sperm?

Hi guys. I've gotten into the habit of masturbating and then cumming into a honey jar. I'm 19 and I want to know if this is normal, I have a jar full of my own sperm that I like to store away in my safe. I don't know if this is normal or not, so please state so! I'd prefer you comment and vote, but if not possible I understand!
