Double whammy :(

Are you sure it's a prolapse and not just a sperm plug?

Here are a couple pictures of a sperm plug from my male:
When I first noticed it-

After I pulled it out-


I mention this because my first reaction when I saw my male was, "Oh no! Not a prolapse!". I was so relieved when I realized it was just a sperm plug.

The tip looks like that but it big and bouljy and the size of a bb pellet bullet. Should i pull it out or gotta go to the vet or put it back in?
