I have a question, it derived from a private discussion I had with another user.
Can clamping be performed manually? (Holding a firm grip at the base of the penis not letting the blood pass) The only problem would be that you get tired.. Are there people practicing this kind of stuff? (I have the impression that manual clamping is safer (you can always release it when you feel something’s not right.. And you have a better tension control).
I am not thinking to start clamping (still a newbie / have much to learn) , but I am curious though.
