How tight to hold it
New here and really going for girth gains.
However, I’m somewhat worried about damaging my penis, especially in girth focused moves due to my high pain tolerance.
So, from other member’s personal experience, how tight do you hold your piece? In some moves it is said that blood shouldn’t be able to pass through your grip. Is that even possible? Is it ineffective to even try to get certain girth gains if my piece is too hard and I can’t visibly see any enlargement when I clinch? Do I absolutely need heat to make gains, and if I’m not sore after did I still accomplish something?
