6.9 cast is finally finished

AITA for refusing to take down my giant penis statue?

Throwaway account because my family knows my actual reddit.

I (27m) have been living with my girlfriend (25f) since the whole corona thing started. Because of corona I lost my current job, so I had to move to hers and took several important belongings of mine. One of which was a giant, 4ft penis statue I got as a birthday gift several years ago. I've kept it with me ever since as I find it pretty humorous. It's hollow inside, so it's relatively light and somewhat easy to carry around.

My girlfriend was entirely on board with having a giant penis statue in her house, she has seen it before and laughed at it so she was delighted when I asked if I could keep it with me in her house. It sits next to the TV in the living room and is hard to miss, easy to spot when you first come in the front door.

Around this time, my mom was also put in a rough spot because of the pandemic and asked me and my gf if she could stay temporarily. My gf was fine with it and allowed her to stay until things got better, however, the moment my mom walked into the door and saw the statue she let out a gasp and nearly dropped her things. She blew up on me and my gf, asking us why we had such crude and inappropriate furniture lying around and how disgusting and immature we were. She demanded we take the statue away or even get rid of it because of how gross it is, however I don't think it's fair for her to dictate what my gf and I should have in our house when we took her in.

My mom has been grumpy about the entire situation, and constantly makes comments and tells us to dump it every chance she gets. My gf tells me that it's my penis statue and in the end it is my decision whether or not I want to keep it. I personally will not be getting rid of it anytime soon, and my mom says I'll ward off guests if I don't.

AITA?
