Vibtator help!!! 🍆🍆🍆

So I'm very new to the sex toy world. I've used a bullet vibrator before and that's it. When masturbating I only like clitoral stimulation as I feel fingering does nothing for me. The weird thing is I can only make myself cum if I'm laying on my stomach and rubbing my clit that way. No other position seems to work. But this way I can make myself cum in less then a minute.

I'm looking to try a vibrator but have no idea where to start. Any recommendations on type?
