King,
I sympathize with your girth issues, we have similar measurements (BPEL 7” EG 4 3/8”). I am also a newbie and just started the “newbie routine” this week. There is some good news, in that according to most of the posts on this forum jelqing by itself can affect girth, albeit probably not as much as more extreme methods like clamping. It’s too soon for me to claim any personal gains, but I certainly feel bigger and fuller after a PE session.
Anyway, take the veteran’s advice and start slow and steady. Take some time to do research on this site and the Internet to see what exercises are available and what you are comfortable doing as well. To be honest, clamping scares the hell out of me right now.
Also, I am just curious, what is your body height and weight. I am a pretty skinny guy (5’ 9” and 135 lbs) and always wondered if my unit was thin because I am. There may be no correlation there at all, but it would certainly motivate me to bulk up more if there was.
