Hi MissFox, my boyfriend and I use Mio as a hands free clitoral vibrator. He doesn't find that it does any of the usual cock ring things for him, such as prolong his orgasm. He barely seems to notice it's there when were having sex. He is more like a 5'' circumference though.

You might also want to look into the we-vibe 3 or the we-vibe 2. less

So I read many of the reviews for the Mio, and I haven't found the answer to this question. I'd like to get a wearable vibrator, that doesn't actually prolong erections. I'm looking for a little hands-free clitoral stimulation during sex, but my boyfriend is a little on the larger side (about 5 1/2" in circumference) and if sex lasted much longer than it already does I wouldn't be able to walk.

So my question is that since from my understanding cock rings can be worn around the shaft or the shaft and balls, the latter we'll be avoiding all-together as it would make things tighter, but I'm curious if it is worn just around the shaft, does it still cut off circulation and prolong erection or does it just become a wearable vibrator?

Hopefully experienced users can help me on this.

Thanks. less
