I've read all the incredible posts about massive orgasms, no touch ejaculation...I bought one.
Although I admit to only using it 3 times, so far it does nothing more than feel like a dildo/plug in my ass. The only difference I notice when cumming is there is more fluid, but not necesarily more sensation.
All that said, I'm not giving up...try, try, again. But I think some of the claims (video/text) are a bit over done/hype. If you really do get such extreme reactions from this toy I'm very happy for you; hopefullly my time will cum (pardon the pun).
