First vibrator

So I’m going shopping with one of my best friends tomorrow and she is EXPERIENCED. I on the other hand am a virgin I’m 16 she’s 17 but she’s very open about her sex life ect. I’m shy and I’m I want to go to Spencer’s if I can get up the courage. She always said she’d get one so I might just give her money and tell her what I’m thinking. I’ve done lots of research any advice for a beginner? I’m looking for more g spot stimulation less clitoral. What can I say I know what I like but my fingers just aren’t cutting it anymore. Also I’m tired of using the bath faucet! Any advice would be greatly appreciated! Not talking to my mom about this so I’ll just find a good hiding spot and save it for when I’m alone. Thanks!
