Stretching with Both Hands

I’m currently doing simple stretching of a few short rounds (15 seconds each). My question is, when do I have to use both of my hands to pull my penis?

If I’m doing 6 rounds of stretch, do I use 1 hand pull for first 3 rounds (15 seconds each round), and 2 hands pull for the next 3 rounds (maybe 10 seconds each round)?

Please help me. Thank you :)

There’s no point you have to use both hands. Though steadily working up to it would be wise. It all depends on how much mass your arm(s) are exerting your unit. If one arm is enough, one arm is enough.

Try adding a few 10 second two-handed stretches in here and there, you know. Build up to it. Use it sparsely but for greater affect.
