   We’re nearly two thirds of the way through NNN! By coincidence, those of you who’ve been faithfully practicing periodic pubic pulsation since this series’s first post have also nearly built two thirds of the all-important foundation from which you’ll tackle more advanced manoeuvres; those who jumped on board later aren’t far behind. (“Pubic puls—eh?” For you, friends, there’s a link to the start of this series at the bottom of this thread.) Exciting as this is, don’t let it distract you from the fundamental habit – all of the sensate training and other exercises in the world won’t do a thing without that steady beat of twenty squeezes done three times a day.

   Yet… by now, you probably have enough awareness and control to feel that there’s more happening during a simple PC squeeze than the name suggests. Just what’s going on down there? Glad you asked, because it’s important; time for a brief detour into… Nether-‘Natomy November.

   :dealwith_cirno:

   All the soft, important bits that’ve been packed between your hips – your pelvic viscera – would soon tumble straight out were it not strapped in by a group of muscles that are together known as your pelvic floor. Each of these muscles do different things, but we’ll focus on two – the pubococcygeus, or PC, and the bulbocavernosus, or BC (more recently known as the bulbospongiosus, but I think you’ll agree that “BS muscle” hasn’t quite the right ring).

   (Aside: Given that we share some of our pubic floor structure with other tailed mammalians, it’s very likely that foxgirls, catgirls, and other tailed ladies would use their coccygeus muscles – another part of the pelvic floor – to move their tails from side to side.)

   Before we dig into the details behind the PC and BC, go ahead and perform a single squeeze as hard as you can, hold it for a few seconds, and then slowly release. Where was the tension? Which parts of you moved? You probably felt something in one or more of these places:

   • The space between your tailbone and anus
   • Either of your anal sphincters (the two rings that close your butthole)
   • Your perineum (taint)
   • If you’re a guy, the area just behind your ballsack (and/or a “pulling” or “jump” of your penis shaft)
   • If you’re a girl, your vagina (and/or a “pulling” or “sucking back” inside it)

   Try a few more times, focusing on each of these places in turn, remembering to fully relax between each squeeze.

   Your PC (pubococcygeus) muscle sits on the top layer of your pelvic floor, stretching between your tailbone and the bottom halves of those two little “loops” at the front of your pelvis (the inferior pubic rami). In guys, its “front” part forms a little hammock that holds the prostate and is therefore known as the levator prostatae (Latin for – you guessed it – “prostate lifter”; the Harry Potter jokes write themselves) or puboprostaticus muscle. In girls, this same part supports part of the back and side vaginal walls and is therefore known as the pubovaginalis muscle.

   It can take a little practice to tell your PC muscle apart from the pubic tangle; a good place to focus is just under your tailbone, behind your anus. When your PC muscle flexes, you’ll be able to feel it pulling against your tailbone there. Since your PC will also pull its colleague muscles in the levator ani complex (which we haven’t time to go into here) up with it, you might also be able to feel your inner anal sphincter move a little. (Vague guidance leads some to mistakenly try exercising their PC by tightening their sphincters directly; take care that you’re feeling that tailbone pull behind your anus that indicates you’re moving your whole PC, not just clenching your rings by mistake!)

   Your PC and its levator ani colleagues also sit between your bladder and most of your urethra, which is why you first found it by pretending you were cutting off your pee mid-stream. Next time you pee, try slowly tightening your PC and try to feel with your new level of awareness how and where it cuts off the flow.

     Now, having learned the difference between our PC and BC muscles, which should we squeeze? Your PC should be the main focus during this three-week foundation, but if you're still only able to move both PC and BC as one bundle, don't worry – you'll gradually be able to feel them separately as you gain strength and control. I recommend that you also try to separately feel and squeeze your BC if you can, though, even partially. The advanced manoeuvres we'll be covering later will depend on your being able to control both muscles independently of each other, sometimes moving separately and sometimes at the same time. But if you can't right now, you can't – don't let that get in the way of your three daily sets of twenty squeezes.

     If it turns out you'd mistaken your BC for your PC, that's completely fine; if you'd never started these exercises, you'd never have reached the point where you could find out, right? Now's the time to get things in order. If you're having trouble feeling your PC at the "back", then pretend you're holding back the fullest bladder you've ever had – slowly clench everything – and hunt for that characteristic pull against your tailbone. Once you've identified it, try to get it to happen along with more and more of your normal-strength squeeze reps; you'll soon find that it becomes straightforward.

     Turns out that I lied – that wasn't brief at all! This part got long, but only as long as it was important. This is a good time to ask questions, if you have any, because we'll soon be starting on the next stage so we can finish NNN with a bang.

     Until then, keep squeezing!

     @wan Does this also build the bulbo cavernosus muscles?

     @CatLord This stage mainly focuses on the pubococcygeus muscle; early focus on an otherwise fully functioning bulbocavernosus muscle, whether by accident or design, tends to be a stumbling block. I'd recommend developing the BC only to the point necessary for reliable conscious control separate to the PC, with room for adjustment later.

     Your BC (bulbocavernosus, now also known as the bulbospongiosus) muscle is split into two symmetrical parts that run along the middle line of the perineum. In guys, it encloses the urethra and helps to pump out its contents, especially during ejaculation. It also presses against the penis's erectile bulb – the lower part of the penis that extends into the body, past the scrotum – and can be flexed to provide a momentary "pump" of extra blood into an erection. In girls, it runs up just behind either side of the vulva, partly looping at the front-facing end of the clitoris. It presses against the clitoris's erectile bulbs (which extend down from behind the visible clitoral glans – the part usually referred to as the "clitoris" – to rest either side of the urethra and vaginal opening) and partly narrows the vaginal opening when flexed, which is why it is sometimes also called the sphincter vaginae or constrictor cunni.

     When your BC muscle flexes, you'll feel it at the "front" as opposed to the PC's distinctive pull at the "back". Guys will feel it as a squeeze in their perineum, usually just behind the balls, or as a "pump" into their penis if done with an erection. Girls will feel it as a slight squeezing around their vulva, or else as a slight pressure on, "pump" into, or "pull" against their clitoris or clitoral hood, though the latter can often only be felt with a clitoral erection, and/or pressure from one leg being crossed over the other at a particular angle, hence the speculative tips for hands-free public masturbation that were at one time a Cosmopolitan staple.

     Clenching the BC muscle can also be used to cut off your pee mid-stream by shutting the urethra directly (if you're a guy) or by indirectly moving along with your external urinary sphincter (if you're a girl). This is why those who've become used to using their BC muscle to delay or cut off peeing might mistakenly identify it as their PC muscle. After you've experimented with your PC muscle to cut urine flow as outlined above, try seeing if you can achieve the same effect with your BC muscle, noting how it's different to using your PC.

     To review:

     • PC (pubococcygeus) muscle: Felt at the "back", between anus and tailbone (but not anal sphincters directly). Supports prostate in guys and part of vagina in girls. Cuts off the bladder (and, in men, the prostate) from most of urethra as part of levator ani group.
     • BC (bulbocavernosus) muscle: Felt at the "front", behind balls (in guys) or around/above vulva (in girls). Pumps out contents of urethra and presses against erect penile bulb in guys, constricts vagina and presses against erect clitoral bulbs in girls. Directly or indirectly cuts off urethra in both sexes, and is so sometimes mistaken for the PC muscle.

     The kind of basic pelvic floor exercises (often dubbed "kegels" whether they're based on Arnold Kegel's work or not) that you can find all over the place don't tend to distinguish between the PC and BC – they just scoop pelvic muscles together into a bundle and then try to "improve" them by working them harder and harder for longer and longer. Girls on this particular treadmill are additionally marketed insertable rocks – sorry, Yoni eggs – Bluetooth-enabled vagina probes, or other hardware made according to the ancient Alibaba.com traditions of mass manufacture and then encouraged to work them out to absurd degrees.

     Remember the introductory post, where in the replies I repeatedly emphasized not over-working your crotch, and the post before this one, where I emphasized completely relaxing the PC between squeezes? From painful penetration in women to premature ejaculation in men, pelvic hypertonicity (too much muscle tone) or otherwise being unable to control when the pelvic muscles tense/relax can cause a lot of sexual trouble. I cannot emphasize enough that this is not pelvic powerlifting; a "more is better" mindset here will eventually bring you to ruin.
