i can no longer get hard while prone

i have been having problems while prone , my dick gets limp after 20 seconds when i start doing it while prone, and i feel like i haven't been making any real progress lately .

my problem is that when i jerk off normally i stay hard for like 2 minutes and i want that number to go down.

any advice on this would be really appreciated
