Help (Limp Clitty)

I've been trying really hard to maintain a limp clitty but I don't feel like I'm getting anywhere. I've listened to Limp Clitty Training loop and Logic of Limp by Goddess Gracie as well as Limp Clitty by Siren.
I jerk off until I get hard but that doesn't last long. And I listen to the files and jerk off constantly.
Are there any other techniques that I should do? I want this so bad!
