Variant of BC excercise
It is my first post here, but I am not novice in PE :)
I would like ask you to try my variant of BC exercises, it is a very god way to find differences between BC and PC muscle.
Stretch your penis upwards and then contract BC muscle for 3 seconds. Try to contract and relax the muscle slowly - you will see that it is not very simple. You will feel every contractions of BC muscle very well because your penis would be going shorter :) . I think it is a good method to locate the BC muscle and to define what is the difference between BC and PC. It is also good technique to feel how to do Kegel’s exercises.
A great post about BC muscle (thanks you Westla): Locating the bc muscle
