I can’t find my sweet spot!!

im having a really hard time locating my sweet spot.

Me Too! and I've been searching for mine for more than ten years. You are not alone in this quest, @B Mayfield 's post on this topic describes, for him, a fairly restricted area of increased sensitivity. He notes in that post the location of this area may have a good deal of variability between individuals. I would add the relative sensitivity may also vary significantly from individual to individual.

Is it possible not to have one?

I think we all have, what I would label, a 'sweet area', that is an area of the perineum which is more sensitive/responsive than other areas. Some men have described it as a dime size area others as a quarter sized area, in my own case I'd say it is a little smaller than a half dollar sized area. Even at that, this is barely more sensitive than any other area of my perineum. For some men, it may take more pressure to stimulate these nerve clusters than our Aneros devices are able to provide. I suspect this may be attributable to the nerve rete of the area being more diffuse over the area thus decreasing sensitivity on a per mm² basis. Your nerve rete may be diffuse as well, but don't worry, you will still be able to get to a Super-O anyway.

And is it a critical component to wrangling in this “super o”?

IMHO, it is not a critical component unless you build it up in your mind as such. Your whole perineum area is laced with sensitive nerve endings and your Aneros device stimulates many nerve clusters regardless of the P-tabs specific location. In the rewiring process your ability to focus upon and then mentally amplify any and all sensations is really the critical component. As long as the P-tab is not producing pain or discomfort, it will do its part to create the sensory feedback loop. It just make take a little more time for the erotic energy buildup to reach Super-O status. Even if you don't get to a Super-O, you can still enjoy the journey along the way there. Remember, even when you do get to a Super-O, the next one is going to be different yet.

Here are a couple of threads with other member's thoughts on the subject -> Beginner having problems, Help a newbie find his sweet spot, How important is the "sweet spot" really?, Having trouble finding my sweet spot and there are numerous others as well.

Good Vibes to You !

Yes, I have found variations in the areas of the perineum directly stimulated by the p-tab of the various massagers. They do not all hit the same "spot". But I don't find that to be too much of a distraction as long as I can feel it "somewhere" down there. After a session begins, I can still feel it and the direct feedback it provides. I concentrate on the overall sensation the p-tab is providing along with the direct stimulation on my prostate. @rumel suggested that it may take more time for the erotic energy to build-up and I would agree. Just think, without a p-tab, the Aneros sessions would not be as complete nor as arousing! Good luck in your journey!

never noticed a sweet spot, and it has never mattered.

that being said, the area in which the aneros pivots can be important for internal contact. some models do better for me if i pull the 'p tab' towards the front of my body so that it rests in a position that is not the natural one it takes upon entry, but everyone is different. my prostate is likely being 'passed by' at the head of the toy, and pulling the tab closer to my front side is positioning the toy in a shorter way so that it is making contact instead of going too far past the prostate.

I think the consensus is that the sweet spot develops through consistent Aneros usage.
In my case, I only really began feeling it when the prostate became really active. It's a sort of chicken-or-the-egg scenario where you might be thinking that feeling the sweet spot will unlock the gates of heaven, when it could be that sensing it only happens when everything else comes along.

But if it maybe helps, involve it in some fantasising. Imagine the perineum is a pussy and somebody you like is stroking it. The body can be weirdly receptive to whatever the mind is focusing on. (Which might not be surprising — we numb pain by trying to not think about it)
