Okay so I found my sisters vibrator and I wanted to try it out. The vibrator was completely dry and I cleaned it off before I used it with some peroxide. I inserted it in me. After using it it dawned on me that my sister is sexually active, from my knowledge she never had an std the worst thing is just a bladder infection. But I'm afraid to ask her if she has anything because then she'll know I used it. Is it possible for me to get an std from using her vibrator even though I cleaned it off?
