Same here.

I've had two roommates who were in the ballpark. As an undergrad I had a roommate whose flaccid member was pretty much the same size as mine, although he claimed that it didn't grow at all when he got an erection, it only got stiffer. I never saw it erect. In grad school I had a roommate who hung about as long as me, but quite thin. I never asked about his erection.
