Great point!
It's been done both ways- deep in subspace as well cold, though He does not force Himself all the way back right from the start- He lets me have my own pace, then He gradually goes deeper.
Yes, He does like to stay in there for long periods of time- not just in and out quickly- and I do hold Him in as long as I can- then finally when I can't breathe (I can't breathe out of my nose b/c my whole airway is blocked) anymore, I pull away... He does not try to pull out very far.
So, next time, I will add the swallowing thing- I just hope I remember!! I am very curious to see how it works.
Thanks Russell!
