I'd say vibe, but if you get the Get a Grip
, which is on sale now, you get the best of both worlds.
The Vibrations hit you where it matters (with patterns too), but as you get more experienced you learn to get the same or better pleasure without the vibes turned on...YMMV, but at least you have the option with this one.
I've tried about 6 prostate massagers and different vibes and none quite compares to the orgasms this gives me. It moves itself with your muscle contractions and has good vrooms. Not all regular vibes hit you in the right spot.
