Thanks for writing back! It is so important for women to know, as you have found out... that Kegelmaster workouts are not drudgery!
It is a "suggestion" to occasionally do the Kegelmaster workout prior to intercourse as this will magnify and intensify the "involuntary" contractions of orgasm during intercourse. Another wonderful characteristic of the pubococcygeus (PC) muscle is that after exercise it tends to remain in a state of semi-contraction, such that you will be at your absolute peak in terms or tightness and responsiveness just after doing the Kegelmaster contractions.
In the next day or two I am going to make a much more comprehensive "post" regarding the incredible sexual benefits of a stronger, well-toned, pubococcygeus muscle.
Incredibly, as Dr. Kegel was doing his breakthrough work regarding incontinence in the 1940's this was considered an unwelcome side effect!
Christi, thank you for excellent questions and for your comments. Please keep up the great work you are doing with the Kegelmaster and write again, soon!
