Whenever I strap into my extender I will initially adjust the screws until my penis is somewhat taught (no slack). However after about 5 minutes I have to re-tighten the screws because my penis has become more flaccid and the extender looses tension (becomes loose). I sometimes have to re-tighten the extender sometime later (like 15-20 minutes later). I was wondering if anyone else has to continually adjust the screws on their penis extenders? I usually wear the extender for an hour. Thanks for your reply!
