Hello brothers! I was working hard to develop an highly intense routine and just noticed something which I never thought of. I noticed that when I use phallogenetics for prolonged period of time, my tunica becomes loose but my ligs don't feel worked out thoroughly. I was using my pf without the spring system and the comfort ring just by tying it to my knee. After prolonged use I just feel my ligs are worked out thoroughly but my tunica doesn't feel the same) I know in traction, an opposite force works which is known as negative tension unlike hanging or tying the penis to the knee for prolonged period. Now the question is, does traction and extension work differently? Any one experienced the same thing? I am now using the both kinds of force regularly
