I guess it really depends on the individual and if you do the exercises properly. Doing it the right way is the difference in gaining or not gaining.
It also depends what you want to achieve first. Correct me if I’m wrong but I don’t think you can work length and girth at the same time effectively. It’s probably more worth your time to focus on one first before the other. Doing a ratio of both exercises. Most people focus on length first before later realizing girth is the pleasure maker and length is for your own ego and appearances. Seeing as length would be less pleasurable over girth when going over average measurements.
Maybe in this sense it’s similar to body building. You can’t gain mass and cut at the same time.
Only reason why I think girth is harder is because you have 3 sections. Base, middle and below the glans girth, which all require different exercises. So it might take longer to even all areas out.
Also the same gains in girth vs length is the difference in volume. So girth gains would be a larger penis volume which thunders does mention in a thread that appears on the main page. So a larger penis does mean more so it would take longer to achieve.
Also I read from some posts that some people with over average girth tend to find girth easier than length.
So far I am finding length hard to get but have a feeling as of recent that my girth might be increasing. My stats r below.
