Definitely do some jelqing. Jelqing will help you in EVERY aspect of PE. Like twatteaser said, it conditions your penis for harder exercizes down the road. Jelqing is VERY important, especially if you’re a beginner. If I were you, I would focus on jelqing alone for at least the first 3 months, and be as consistent as possible. If that means that you only do 15, 10, or even just 5 minutes of it a day, then fine. But do it EVERY DAY. That’s the one thing that really gets a lot of people, and why a lot of people don’t gain, they simply aren’t consistent in their routines. And especially with your girth, you needn’t worry about anything else but basic jelqing. Your girth might actually gain a little from basic jelqing along with length gains…that’s what happened to me. :)
Now, the only thing I see that might be bad on your part is that you’re dry jelqing. That’s actually a bad idea if you’re a beginner IMHO. It’s more intense and actually hits your girth harder than your length, which you don’t really want, trust me.
If I were you, I would do some WET jelqing for at least the first 6 months. That way, you will definitely gain some length (at least I’m pretty sure…I’ve never heard of someone NOT gaining length from regular wet jelqing)…and your penis, after 6 months, will be more than ready for anything you want to do with it.
Just like everything else, you HAVE to start with the basics and work your way up. Trust me, if you try to start out with high-level high-intensity exercizes, you will burn yourself out, and quite possibly injure your cock. There have been instances of guys hurting themselves from so much PEing, that they can’t even get an erection anymore…they just totally killed their whole area down there. Don’t be one of those guys, be careful, go slow, start out with beginner exercizes and slowly work your way up to harder and harder ones.
If you follow through with this, you will be very successful with your gains. You’ve already got some considerable girth working for you. With enough time (years, mind you), you might be able to get up to 7 or even 8 inches in girth. Whether or not you’d want that is up to you. Also, your length could get worked up to 8 or 9 inches with enough time, if you just stick with it, be safe and etc etc. =P
As far as doing stretches goes, stretches are good but they only stretch the ligs and whatever else is down there…it doesn’t actually do anything other than temporarily stretch your penis out a little more, but it will easily revert. Only with jelqing, especially wet, will you cement gains. Stretches in PE are just like stretches in regular exercize…you use them as a warm-up or just to help “roll out” your penis every now and then, keeping your cock nice and pliable, but you can’t depend on that solely for gains. It just doesn’t work that way man.
BTW I hope my post isn't too incomprehensible…I'm pretty hungover and the drugs are still spinning around in my system…lol…hope my posts helps you out man.
