Help a girl out here with her womanly probz

My sex life is basically nonexistent now and I need help with vibrator recommendations. I’m embarrassed to even admit all of this. 😬

I don’t know what’s out there, and I have never used one before but I don’t remember the last time I orgasmed so ya girl here is pretty...pent up. I need something waterproof and discreet. Any recommendations?

Also, does a vibrator go IN the vagina or around it? 🤪
