Should I refrain from big toys?

So I have been into anal play long time, I can have 12″ level toys, so yes big stuff. But of course the Super O with aneros would be the ultimate goal. No luck yet. Think I also need to discipline myself more on kegels + reverse kegels. But I also wonder, should I refrain from the big toys? These must have some effect or not?
These days my sessions mostly start out with aneros > njoy pure wand > dildo stuff > maybe some more pure wand.
And while we are at questions, chastity I am also wearing to prevent penile stimulation, but it can be distracting? I guess getting a erection is a good sign when using aneros (although it might be because of the porn I’m watching). But it can be annoying/painfull.

Force myself to try longer

So my discipline is really bad, I give in to fast. I only had one session like a year ago were I possibly had a p wave or something that felt awesome. Lately not so much success with aneros, did discover squirting with Njoy wand.
But tonight I’m gonna try to tie myself up to the bed with a time lock. Maybe like an hour?
Only things I worry about:
Aneros slipping out (I will use maximus)
Getting dry, haven’t found the perfect lube yet I think?
Overdosing on weed (I use thc oil, if I have just one drop too many I get nauseous, 🤢) but I think I know how much to take.
