i started hanging about a month ago and was hanging straight out my bpsfl was like just over 9" like maybe 91/4 at a hard stretch but as i was hanging everyday for the last month i re measured and i can only stetch to 9" bpsfl. when i felt too tired i used lighter weight for a day and the next day i would hang at the original weight am i supposed to have actual rest days when i hang and dont hang completely cus i read on bibs forum and he says to hang light to keep the penis in extended state. im just a bit worried that i seem to be losing the stretchability or something, help please
