Ok so I used the Aneros syn a couple times and it didn't really do anything. Except that one time where I masturbated with it in, I noticed the next time I inserted the Aneros it was a lot better, so I decided do it again.
Instead I get a completely different situation. During masturbation I could feel the Aneros hitting against my prostate, and for the first time I think I felt direct prostate stimulation. The weird part came when I ejaculated.
All the sudden the Aneros started vibrating, which is weird because it's non-electric. Very localized where the Aneros was. Overall it was an unsatisfactory orgasm, which I'm not complaining, but I added it for details.
Can anyone tell what that was?Source: http://www.reddit.com/r/aneros/comments/3bay88/what_the_hell_was_that/
