some possibly useful information l want to verify (might help others)

@Auroken, I feel that the instructions and information is too general. As far as I have discovered the PC muscle is a generalized name give to the pelvic floor muscle system. The target muscle should be the BC muscle which equates with the inner penis bulb. Generally I think it hast to be identified with an erection as you say it moves or lengthens the erection. Females also have this muscle and I think it is very small and just in front of the vagina (edit: each side and up to clitoris). Now I am not medically trained but sometime ago I came across a detailed description of the BC muscle, it's location and its function. I have a diagram of it. It seems as if many folk don't get to isolate it and strengthen it. As we never speak of it I have tendered to forget it. Thank you for reminding me get get to work with it again.
Caveat - if I am wrong, well, disregard!

would be pretty interesting to acquire more information on this, ld like to know if lm looking towards the right area on both tab placement and with regards to working the right muscles.

@Auroken, the explicit diagram I got was on the open web but is now locked away in a membership site. I am not sure I can post it as it is no longer publicaly available. Let me see if I can find the site. The person posting was making the point that it is muscle that is over looked because of the PC generalization. I personally think there are a number of minor muscles associated with the B/C and prostate that have huge potential but need some very sensitive awakening. I don't think strenuous Kegels would be the way. But then I may be fantasising, or wishful thinking. *-:)

Not as detailed as I would like but gives the general idea. I can sort of connect with it without having an erection.
You may be right, the sweet spot being the "notch", that is, the end of the BC muscle.

Really glad for this discussion. Thanks guys. @AneRico you definitely can tone that muscle. It seems to take me forever to isolate it (I started looking for it while reading the Male Multiple Orgasm book) so I don't get the time to do it that often. If you are sitting or lying on your back, and it is the one I am thinking of, it causes your scrotum to bounce or pull up toward your cock. You can get it twitching which feels great but for me it is always trial and error while slowly working over the PC muscle.
I completely agree with the comments in the post. I spent the first couple months focused on the rectum thinking it was the PC muscle. It wasn't until I read that the PC muscle was more like a hammock that I started to have better results. I visualized a hammock suspended from 2 points. One point was my anus/rectum and the other point was the PC muscle that closes off urine flow/makes the cock bounce and ejaculate. Then I imagined the Aneros was like a bowling ball suspended in the hammock and I practiced moving it back and forth/up and down the hammock by slowly alternating between a gentle PC contraction and a gentle rectum contraction.
Although the rectum/anal pulsing is wonderful, I continue to feel more focused progress toward new experiences with the PC muscle and that muscle that makes the balls jump and twitch.
Thank you all for this post. It has me refocused after a 2 week break. Today my prostate was twitching as I watched television so I guess it is time to feed the beast 🙂

I am truly fascinated, perhaps amazed. There seems to be a huge denial of the key penis muscle. Perhaps it is our Puritan influence, or perhaps the name. Perhaps it might be an idea to call it the BCE muscle to remove the religious connotation! As far as I can see the BC(?E) muscle is the muscle that forms part of our penis. It would be good if we dared to find and focus on this muscle as well as the general PC muscles. It can be difficult to locate but it makes it harder in in our quest we keep referring to it in general terms. Once we can locate and identify the BC muscles I think we will find there are a number of minor muscles that make it up which seem to be connected to the prostate, at least that what if feels like. I do not have any diagrams of the top side of the BC so I am flying blind, however as all parts of our body are interrelated and connected the top of the BC should lie against the prostate and the functions of each relate to each other in urination, erection, ejaculation and orgasm.
Sorry about this but I think it would be helpful to call a spade a spade and not earth moving equipment.
PLEASE take this with a grain of salt. If it is not helpful just disregard it as an old man's dementia!

It is always very good to study diagrams of our anatomy which center upon a man's prostate and the areas surrounding that organ. I appreciate very much both @Auroken and @isvara sharing with us diagrams of the PC and BC muscles central optimal sexual function in the male.

I share right now with all of you the Wikipedia article on the seminal vescicle which shows the prostate and auxiliary organs in clear relief. So wherever I have an Aneros session, I enjoy visualizing in my mind how each Aneros model works over my prostate. I find all this very arousing.

In the first six to seven months in my Aneros journey, I used to do the Kegel Exercises religiously. I found the Progasm models well-suited for the Kegel Exercises. But since then I use them just briefly in sessions focusing upon how well they have ridden me.

Wow, @beegee6! You have given us some powerful meditations on how to exercise and tone our PC muscles in a delicate and subtle way. I am going to have to copy down what you have written in my notebook for further reference!

I have noticed in the last several months, certainly when I added by the Peridise Full Set and the Tempo to my sessions that not only are my PC and BC are well-toned but also they feel like big rubber bands which give me awesome control over my Anerosing. Now I focus upon my shallow, subtle breathing which powers my Anerosing these days.

seem like i have heard someone on here speak of a front and back PC muscle that can be controlled separately. I guess if the PC muscle group is hammock shaped that would make sense, one muscle in the front and one in the back. Good discussion.
