Conservative parents found my dildo

I share a house with my parents because we're financially codependent to survive. Every time a homosexual comes on TV, they either change the channel with a look of disgust or make some homophobic remark before muting the tv. They call Ellen Degeneres "Ellen Degenerate" and call every gay person a queer. Standard homophobic stuff. In an act of protection for my straight sister who dared to have a straight relationship, I said that was nothing and came out as gay. They were in denial, said I just said it to protect my sister (which was partially the reason) and that I didn't really mean it, asked me if I had ever abused a child, told me to never tell anyone else because of family reputation, and began pushing the girlfriend angle on me.While I was at work two days ago, they decorated some of the house for christmas, including my room. When I got home, they showed me everything they did, and said "we absolutely love you son, thank you for everything you do" and then my mom followed up with "I might need a drink to forget what I saw in your room, though" and gave a nervous laugh. I gave no sign of awareness, and apologized for the messy room. "Oh, that wasn't it, but it's ok, we love you." After they left my room and went out of earshot, I checked my hiding place - it was still there, covered up in the back of a drawer as I left it. I figured they might have seen my Dungeons and Dragons manuals I keep tucked away behind my bookshelf, as my mom believes they're satanic, and gave a sigh of relief.Last night I was a little drunk, so I tucked it away behind my pillow instead of its usual hiding spot and passed out. In the morning, I woke up from a dream so vivid it made me forget I placed it there. When I got back from work tonight, I saw that my mom had done more decorating, and that the covers and pillows were moved away, absolutely exposing it.There's no denying that they know about it now. I suppose they can't kick me out because they need me as much as I need them to survive, but what on earth do I do in this awkward situation?
