I’m one of the “fussy ones” because the PC and BC (not PB) are different muscles and have different functions. You’re free to call it what you like, but to be correct the muscle in question is the bulbocavernosus (BC) which is also known as the bulbospongiosus. This muscle (actually one muscle on each side of the body joined together that work as one) contracts at the time of ejaculation to force the semen out of the urethra. It is also used to clear the urethra of urine at the end of the process of emptying the bladder. You contract it to give that last squirt of urine to make sure the urethra is empty.
A kegel (named after Dr. Arnold Kegel, a California gynecologist) is the conscious contraction of the BC (in men, in women it is the PC - [urol=/forum/showthread.php?t=16232]see this[/url]). Men do kegels to strengthen their BC muscles for a more forceful ejaculation and also to become more aware of where it is and what it does. Ejaculation control is achieved (if you time it right) by strongly contracting the BC so it cannot go into the rhythmic spasms of orgasm/ejaculation. By putting it into an already contracted state, you (sometimes) can prevent ejaculation. In some men, who have practiced the technique and understand the timing, this can prevent the post-ejaculation refractory period where the erection is lost and another cannot be attained for a certain length of time.
A “reverse kegel” is simply not contracting the BC muscle. If this is consciously done at the time of ejaculation then the semen will often “flow” from the urethra instead of shooting out in spurts. It takes some practice to overcome the natural rhythmic contractions of ejaculation. It’s fun to do, but serves no real purpose and it does not prevent ejaculation or help control it.
The use of the reverse kegel in PE exercises was advocated by former member doublelongdaddy (dld) in this thread. He felt that by relaxing the BC muscle while putting traction on the penis that it would help in length gains. I’ve never really examined that theory until now, but it seems to me that relaxing the BC would actually have little impact on length gains by manual stretching (or any other traction method).
If you look at this image you’ll see that the bulbocavernosus muscle surrounds the bulb of the penis which is an extension of the corpus spongiosum (CS). The CS is separate from the two main erectile chambers (the corpora cavernosa, CC) and extends from the bulb to the glans (head) and incorporates the urethra. The BC is attached to a ligament (called the central point of the perineum) to which other muscles are also attached. The ischiocavernosus muscles (see the illustration) surround the crura (or legs) of the penis which are the two ends of the CC. The crura are firmly attached to the pelvic bone.
Since the CC form the main body of the penis and are attached to bone, relaxing a muscle that surrounds the bulb, which is attached only to a ligament and via that ligament to other muscles, will not prevent the bone-attached part of the penis from resisting the pull of the manual stretch or hanging. In other words, doing a reverse kegel for PE does not make it easier to achieve length gains and would have no effect at all on girth gains. It was an idea one member had who thought it would help, but if one examines the anatomy it’s pretty clear that relaxing the BC won’t make any difference when traction is applied.
It’s true that you can kegel while applying traction (those with a strong BC will see more of a tugback), but the fact remains that the main penile structures, the CC, are still attached to bone and relaxing or contracting the BC won’t change that.
