Ozzy83, I usually stretch very hard. Not rip your penis off the bone hard, but I will stretch until it feels as if there's no where else to go. Once I reach that point then I attempt to take it a bit further. There is no real way to say exactly how much tension you should use, but my guideline is to pull to maximum stretch, which is the current max FSL, and then go a bit beyond that point. Now, there won't be a huge "give" at this point as the penis is at it's maximum length, however you can attempt to take a bit beyond that and that's where gains are made. Length of session doesn't really matter, as long as you feel good and stretched at the end. I've had sessions where this happens in 5 minutes, or in 35 minutes. It all depends on how your penis is responding to the work you are putting in. Now, the key to this method is to not focus on how hard or how long but to focus on the feeling your penis is giving you. If you're sore at the base, in all likelihood you'll be better off with a lighter stretching day. If you are not getting much feedback from your penis, you might spend a little bit more time stretching. If your penis feels tight and lacks any sort of spring back or "slack" then you might think of taking a day off. It's all relevant to where you are in the healing cycle.
10inch, Try spending a little less time on girth, at least using any intense methods, as one of the lessons I took from BIB was to not attempt both girth and length at the same time as this will slow progress. If we keep it simple, and stay headed in one direction, we can achieve a goal more directly than if we were to split our attentions in two different directions simultaneously. I've been working length only for the better part of a year, and I've gotten nearly another 1" in FSL in that time and over .5" in EL in that same time. That rate of return is better than my two year streak of no length gains and only moderate girth gains. I really do think that attempting both is counterproductive. I will say that using the jelq, usually no more than 300 at a session, is a great way to promote a healthy penis and add small amounts of girth. As I've said before I've found it to be a solid way of aiding the conversion from FSL to EL.
