I am not looking for much in the way of erect gains as my partner already says she feels close to max capacity, and no partner I've had ever felt like I needed any extra. Having said that, psychologically it might be good to be clearly the right side of 8 inches without any shenanigans with the ruler.
What I would like is for my soft or soft-looking size to more consistently replicate my hard size - which it already does quite well - for purposes of exhibitionist acts. Encouragingly, that is the area where I've actually seen jelqing make a (slight) difference, which is the main reason I continue to do it even though I can only maintain a gentle and prertty inconsisent routine. I hear that the (long-term) gains from pumping are also in this area so I may try it at some point.
So yeh - 8.3 inches both hard and soft. Anyone who doesn't think this is huge enough is nuts. An 8.3 inch floppy cock would be breathtaking.
