I did some basic PE stretches for about 8 months when I was younger, but haven't done any in about six years. My penis has remained the same length and girth for that six years, but I am curious as to if any possible "gains" I made during those 8 months could be lost by now. Has it been too long since I have done stretches for length/girth to be lost? I have seen questions similar to this one in other threads, and people say they have lost length/girth a few months after stopping. Is six years too long for me to lose anything/would I have lost it long ago if I did make any gains?
