P.C. or B.C. ?
I have had the intention to post this little lecture for quite some time. This question gives me the opportunity to help everyone understand the difference between men and women concerning the PC (pubococcygeus) muscle and the BC (bulbocavernosus) muscle.
There are three illustrations. They are attached to this and the next two posts. The fourth post down contains the explanation of why women contract their PC muscles to strengthen their vaginal and urinary systems and men contract their BC muscles for better ejaculation and stronger erections (and to test their LOT).
