wen im focusing on girth i like to start with a little strecth routine before i start jelqing like rotary strecthes just loosen everything up so you can get the most out of ur jelqing and still keep length gains:)
yea dude same thing happenned to me i stopped strecthing to focus on girth and lost about an inch on length but wen i started strecthing again it came back within a week...i think its the ligs tightening like you said
