Anyone else use a vibrator during sex?

Hellloooo ladies. So I only hit the big "O" when I have clitoral stimulation, when me and my man have sex I'll hold a vibrator on my clit (feels amazing especially with him going in and out) anyway, I was wondering if anyone else does this?
 Also, my vibrator is pretty big so when he's on top it's annoying to hold this big thing on my clit... Does anyone have any suggestions on a vibrator that's small that would be easier to hold? 
Thank you!
