How is anyone getting hard inside one of those things? Try as I might, it's just not working for me when I have a dry piece of cardboard around my dick.
People: please stop saying "I'm so damn big I can't get it in flaccid." Yes you can! You might enjoy boosting your own ego, but flaccid you can fit in to almost anything. That doesn't mean it will drop gracefully through the roll, but you can squish your dick, stretch it out, whatever. Squeeze the top couple inches so they're thin, push it through a bit, then reach your fingers through the other end and pull. The reason I can't fit it through when erect is because the roll's too tight and I'm hard. Soft it takes some work but is doable even on the thinner rolls they sell at costco.
As much as I'm bothered by ridiculous dick myths about erections, it's the nonsense about flaccid dicks that bothers me the most. Slightly OT but all those guys whose entire galleries are only pictures of them 'not even fully hard' (you know who you are) are the worst offenders. Seriously - did you come here do brag about how huge your spongy erections are?
