Hi quick question

Welcome pavlo,
Sounds just right.
Insert Helix about half-way and if you're properly lubed it will seek it's own correct position. Depending on your inside dimensions that will leave 1/4" to 3/4" 'hangin' out. 'The only thing to check is that you have complete p-tab contact with your sweet spot. Enjoy !! hth .. rook

Hi pavlo,

Welcome to the Forum,
This image from the Aneros HOME page accurately depicts the proper insertion location.
The tip of the Aneros (while inside the rectum) pushes against the prostate gland. The walls of the rectum are very flexible and elastic, they will easily stretch to accommodate the shape of the Aneros. When the anal sphincter muscles are contracted, the Aneros with its P-tab arm is pushed up into the prostate and thus massages it. The P-tab also acts as an anchor/fulcrum/pivot point. When the contraction takes place the Aneros will rotate slightly about the center point of the P-tab thus pushing the tip of the Aneros forward into the prostate for added massage action. With both the Helix & Eupho models it is not necessary (nor really practical) to attempt to insert all the way to the "T" junction.

Upon insertion of your Aneros the proper orientation occurs automatically and naturally. The Aneros are already designed with a forward canted shape to be directed at the prostate, the P-tab assures correct orientation and alignment. Pinpoint accuracy of prostate engagement is NOT necessary. It does NOT require much force or pressure to stimulate the prostate sufficiently to generate the P-Wave phenomenon. As you become more experienced with your massager you will find it requires less and less pressure to generate P-waves, to the point you will be able to generate them without the Aneros present at all.

P.S. I sent you an introductory PM with some additional hints and tips to get you started.

Thank you rummel and rook ansered my question perfectly!!!!!!!!!!
