It 'is' okay that I get an erection to help put on my extender, right?

Topic.

It just makes things easier. I begin strapping-in while having an erection, but I tighten the straps when my dick begins to flaccid-ize.

yes, a semi is good to make fastening into the cradle easier.

To set it up it should be OK but you will need to make sure when your penis deflates it does not slide out of the strap. You do not need to go fully erect for this.
