Help with getting started

I’ve read up on the aneros beginners forum and listened to multiple podcasts, but I’m hoping for a little more specific feedback.

I ordered the Helix Syn V and I’ve used it 3 nights in a row so far. I’ve been mostly trying to learn to distinguish my different pelvic floor muscles and to incorporate them with using my aneros. I think I’m heading in the right direction (?) because I’ll generate precum multiple times in a session, but I can’t seem to get much further than that aside from the occasional ripple of tingling sensation throughout my body that I’ve felt before when I really had to pee but held it. I know it’s a journey, but I was hoping more experienced users could help point me in the right direction with a few things.

Do I need an erection for this work? I’ve enjoyed listening to erotica and trying perineal massage, but I’m not always hard when I do it.

Why does everyone mention binaural beats? Just because it’s relaxing? Will I not achieve the same result lying in bed?

Are the vibrating settings helpful or more for enjoyment once I’ve rewired?

Should I try blue balling myself and then focusing on the pelvic floor muscles? Or should I be totally disassociating my cock and prostate?
