My overly religious, very sheltered and very conservative mother found my vibrator

So, a little background story about me. I am basically, a goody two shoes who as far as my mother is concerned, has no sexual desires what so ever. I am the golden child with the straight A's, a hefty college resume, and the perfect straight child who will only date after obtaining a college degree and 100% under the lord. Needless to say she was wrong on a few things. One: I have very sexual needs, and Two: im not straight nor religious (atheist.) See, I am a curious 18 year old girl, and a virgin to boot. I have multiple fantasies and I also wanted to know my body and what i liked, but i didnt want a partner to discover such things. Which is why I got the toys to begin with. So. About the vibrator. I bought a purple 8 inch, penetrable vibrator thats seriously recommended by the ladies. I suppose judging by its appearance she thought I was a lesbian (she's partially right, I am bisexual.) She started accusing me about my sexuality and that I am going to hell a lot of nasty things. I got very upset and I stopped talking to her for about a week until we eased into an uneasy impasse. She stole my keys so I could never open the safe. Right after that she stopped trusting me. She started opening my letters from college, she didnt believe the money from my fafsa was not from a boy im looking, and when I started my AP testing she called the school because she didnt believe me, and thought I was skipping. I was so tired and dammit I wanted to be me, so I decided to hell with it and I bought some replacement keys. The people who I bought it from said it would take 2-3 weeks to arrive but the damn keys arrived in 3 days. She found those too but she hasnt said anything yet. My sister just told me about it today (she has no idea whats in the safe so she thinks its hilarious) but Im freaking out. Again. So, I am waiting for the onslaught. I honestly have no idea what to do. I just know its going to be a repeat from last times x3. Its the worst. Any help will be seriously appreciated.

I take it the safe contains this vibrator? If so, why did you go to the lengthy trouble of ordering new keys? Wouldn't it have been faster and easier to have just ordered a replacement vibrator and hidden it better? This isn't about your sex life or (as yet un-established and -confirmed) sexual persuasion. It's about the fact that your mother is a SMOTHER. If you're living under her roof at her expense, and if you cannot appeal to your father for his help in trying to reason with her, there's not a lot you can do apart from leave home and go and - whilst awaiting your degree in order to get a full-time job (which already at 18 you're certainly old enough to do) - live with whatever sympathetic friend or relative. I in fact suspect that if your mother KNEW she was pushing you to that extreme, she might well decide to start to compromise rather than thinking you're her mere puppet.
