I don't remember if I was ever able to pack a 2" with my head, too. Would likely take longer than a 15-min session. I haven't done longer sessions for many years because I don't like the "donut" ... but recently I've renewed my search for the perfect sized rubber band for that area just behind the corona and covering what's left of my frenulum. If I can find the right size, I might go back to stuffing now and then ... it sure looks awesome!
