Regarding the positioning of the helix trident

So, yesterday I finally got around to trying the helix trident I got. In a previous post I described how in regards to the PC muscles I don’t have any voluntary control but I figured it would be fine after contacting the Aneros support team.

So, I lubed up and inserted it and to my surprise I found that while the perineum tab was in place, the K-tab was sticking out a bit and it seemed as though my sphincter had trouble holding it in place. In general it seemed to stick out much further than I thought it would. Is that supposed to happen?
