Preventing erections behind the base ring

Hi everyone, I picked up the holy trainer v4 recently. Upon putting it on, I noticed my penis could still achieve hardness behind the base ring. I swapped in a bigger base ring to see if that would help, but it didn’t make much difference; I can still get hard at the shaft of the penis, just right behind where the base ring sits. Maybe I should cut back on the lube? Or do you have any other tips? Thanks so much.
