New user struggling with patience/focus

Hi! I got my Helix Syn V about a month ago and have done a handful of sessions. However they have all gone like this:

I start watching some porn until I’ve been aroused for several minutes. I insert the aneros, lie back, and focus on my breathing and sensations for about 10 minutes, then begin to play with contractions.

If I turn the porn off at this point, I just get sleepy and find it impossible to focus.

If I leave the porn on, I get dick-horny and run out of willpower within half an hour, finishing myself off with a traditional orgasm.

Did any of you experienced users struggle with this starting out? What did you change going forward to help with it? TIA
