I’m new, as well. This is a question I was thinking about, myself.
There exists the temptation to double up. During my first session, I was amazed how tight my ligaments are. The amount of stretch and relaxation at the base increased quite a bit during stretch/exercise. This got me thinking about twice a day. However, given how inefficient I’m sure I was, and the comments here, once a day makes sense.
There is a lot of potential for general penile health and strength here, whether looking for gains or not. It’s going to take a while to generate consistent jelqs; mine ranged from lame to obviously productive. Frankly, it was a shocker to get one close to ‘right’. The instruction and anecdotal info found here comes into focus.
Great site.
