So that was crazy... (Added details)

Rundown: I've lived with my bf about a year and a half. 
I just went to take a shower and saw a huge butt plug dildo thing hanging on the door. I never knew about this fetish. I confronted him like it was no big deal and he got all excited and showed me his stash of like four of them. All different sizes ranging from little to a huge one the size of a black guy porn star kind. He wants me to use them on him. I'm a little freaked out.....idk what to think right now!!😮
