Here’s another thought, lifted from another thread (Kojack10 - 1/2 inch in one month - only 5 minutes/day). Rather than three hours at a time, how about three hours split into short segments over the course of a day?

1. Studies on the cyclic loading of tissues suggest that most deformation occurs in the first stretch, and after four stretches there is little change in ultimate length. Therefore there is no extra benefit from stretching a muscle 10 times in one session.
2. It takes 12-18 seconds to reach stress relaxation, so there is no need to hold a stretch for longer than 20 seconds.
3. Greater peak tensions and more energy are absorbed the faster the rate of stretch. This means that a tissue will generate greater tension if the rate of stretch is faster and therefore not achieve the same length as a tissue undergoing a slow stretch. That is, do passive stretches SLOWLY.
4. Once elongated, length changes are not rapidly reversible due to the viscous nature of the tissue. However, deformations are not permanent because the elastic properties will eventually bring the tissue back to its original length. Lasting changes come from adaptive remodelling of the connective tissues, not mechanical deformation. One study in South Africa showed that stretching every four hours was the most effective way to achieve elongation in a muscle. This may suggest that the temporary change in length following a stretch may start to regress after four hours (Grace Hughes, unpublished study).
Peak Performance - Flexibility and stretching: the science behind the importance of keeping flexible
And yes, I know; the penis is not a muscle. Still, food for thought, and a possible alternate approach to longer duration pumping.
And the beauty of this approach is that while you’re asleep, nocturnal erections take care of stretching things for you (at least somewhat) periodically during the night.
