Aneros Syn isn’t long enough?

So I was having a pretty fun session last night, and while being high on marijuana I think i made a new discovery. If I squeezed my aneros incredibly deep within me, it just barely scraped a spot that made me shiver. I’ve had prostate orgasms (or whatever kind of orgasm) I was getting before with my syn, but I’m starting to get the feeling that my Helix Syn just might not be long enough. Has anyone here had experiences where they needed a longer toy? Unfortunately, Aneros doesn’t really make products longer than 4 inches, which is a bummer cause most longer toys aren’t hands free unfortunately.
