Beginner with Sex Toy

So i’m 19 and I just bought a mini bullet vibrator. I was just using my legs and pressure to…get my self off before. But then I wanted to see what all the hype with vibrators was all about. I tried it and it didn’t go well..it didn’t feel good, i didn’t climax and it just made my private area kinda numb. I don’t know what i did wrong or if i’m using it right? Is there a specific way to use a vibrator? Pleassee help me yall!!😭😭
