Well I find it very difficult to contract both. We had many pics in this thread. The BC is directly behind your balls. The IC is on top and the sides of the dick.
The pc muscle is much more near to the anus.
I isolated both BC and IC but cant hold both at ones.
While an erection is occuring it is to my udnerstanding that both muscles contract very subtile in an alternating way.
Im think, for the people who heard of balooning, that that is alternating BC and IC muscle..
