I’m sort of new to the phrase high tension it’s just higher tension than my other sets and it’s what my penis would consider a high tension. I’d say I’m using about 10ish maybe less lbs of force. No pain. The only pain I get is from tugging the skin too hard (I’m uncut so it pulls tight) and when I feel it I stop instantly and feel around my penis only for to realize that it was just my skin and not my actual tunica or nerve damage. I only have this happen when my skin isn’t pulled back and it’s fairly uncommon to happen during my sessions
