Vibration actually helping to rewire?

Tonight I had a session with the Progasm, I had a little weed beforehand too. The session was going pretty well, but not amazing when I decided to try my GFs bullet vibe on the outside. I find I"m only getting involuntaries briefly, but when I had the bullet vibe down on the outside of my ass touching both the outside of my anus and pushing on the progasm, it seems to generate involntary movements very easily. I was having a great fantasy there I was a woman use the vibe on my clit while a dick (the self moving Progasm) was a guy fucking me. I started getting a good build up and the involuntaries got more rhythmic and like they were trying to build up which I believe. I was really digging the fantasy and ejoying but something (outside of the session) startled me and I couldn't get back in the zone.

Are involuntaries that are stimulated with the help of the vibe still a good sign or should I avoid this? The vibe was on a quite low setting.

Reading over the range of early Vice previews it looks like there's a good variation in how different we are when it comes to using a vibe. While getting numb or desensitized isn't helpful, there seems to be some low threshold that works for some gents. Were I getting involuntaries I'd go with it. Personally, vibe hasn't worked for me around either my penis or prostate. B.F. Mayfield's review seems to point to the very muted vibe modes as being a real plus. My 'brown box' is still being held captive by the Post Office so I've no clue on this one.

I'm in the same boat as Rook. My Vice is traveling from Houston to Little Rock via Chicago. Though i'm no rocket surgeon and I may be behind on the latest discoveries in geography, but it seems like the shortest path between two points rarely includes Chicago. I'm just hoping that it's doing something important while it's there, like throwing the One ring into Mt. Doom.

I'm gonna try the vibe again next time I think. The amount of vibration getting through to the prostate was quite low, it was more so concentrated on the outside and it really caused the progasm to push and pull and I know it was involuntary cause trying to build with it would cause it to stop. But if I just relaxed almost totally, enjoyed the slight buzz and the fantasy it would just start pushing and pulling on it's on, very cool. I could also try it with my Helix cause I can wedge the vibe right in the tail but I like the progasm better and I think its the vibration on the outside moreso than that prostate that is working here. I kind of want to put a mirror down there and see how much the Progasm was moving cause it felt very good.
