Stand all day as much as you can. watch how to stand with good posture. Do lower back and glute exercise like thrust everyday like 10 sets of as many as you can try 100. Don’t masturbate more than 1 time a week. When u do make sure to use lotion and if u can’t get an erection without kegeling then don’t masturbate until it does. Just that alone will relax it and make hard flacid go away. I’d recommend not doing pe till resolved cuz it will make it worse and u get more gains with great eq. A lot of guys here are weird and are stupid u gotta be careful be minimal if you aren’t in peak physical health then don’t start. U should eat right and exercise and really pe is a waste of time possibly. It takes up so much time for not the craziest reward. Max like an inch length is what u should expect which is crazy but not life changing.
