I'm going to buy and use a vibrator when I was specifically told not to
Why would you be told not to? Have you ever used one before?
No, but I want to get a new vibrator
Adults are allowed to do what they want with their own bodies. Nobody should tell you or make you feel guilty for doing what you want.
Yeah, I shouldn't be ashamed for the amount of sex I'm having.
Yup. Maybe don't tell everyone else about what you are doing it might make them uncomfortable.
