I know exactly what you mean. The main purpose for med with PE is increasing the size of my flaccid penis. If my morning flaccid would be my normal state I’d be more than happy. No luck in that department yet.
If I understand you correctly you gained in erect state but not in flaccid? From what I’ve read here it’s usually the other way around. People often claim that flaccid gains is an indication of upcoming erect gains. Another saying about PE is that with time, you might very well go from being a grower to being a shower.
Another way to look at it is taking the varying flaccid size as a good thing. It’s the penis natural defense mechanism to turtle up when being cold or when blood is needed in other parts of the body. Anxiety is another cause of turtling.
Other stuff for increasing the flaccid hang that usually come up around here: drink lots of water, don’t jack off too much, L-arginine, fowfers, don’t use underwear.
