No i do not use any lube. The lube I was speaking of was is the clear lube that our penis puts forth naturally when getting an erection for a while. I am assuming eveyone’s did does this, mine does anyway.
Yes, it does take a much firmer grip. I cannot get my hand pushed all the way into the fat pad either but I go as far as I can. And yes, this technique does give me a nice constant expansion.
