Need help with width issue

[wickedshooter]

Hey all, I've been experimenting with depth and thickness play but im having a problem that I need some advice on. Any time I try to fit something bigger than about 2.5 inches in diameter, the hole doesnt have any problem but I run into my tailbone and cant get the toy in. Ive tried several times but keep having the same issue. Has anyone had/solved this problem themselves? Any advice or help would be greatly appreciated! Thank you!

If your hitting your tailbone and it stops there, I don't think there's much you could do about it. That sounds like it will make it physically impossible.
