Is it normal for me & my bf to make stuffed animals have "sex" and record it?

Somehow me and my boyfriend end up with a lot of stuffed animals, and when we are really bored we make them have sex supposedly. Well last night I got a new stuffed toy and we were so bored we recorded the new toy getting sexed by all the other stuffed toys. My boyfriend was getting all into it. I had to stop the video because it was too long. 17mins! Is this normal?? We were just so very bored. I'm 18, he is 19.
