So my boyfriend has a pretty good sized schlong (I won't share exactly, because that wouldn't be right!), but I noticed something the other day. When he's out in the cold weather and comes back inside, his penis is longer that it usually is - but he's still flaccid. It's not even a semi. Like, if we're just indoors all day, his dick will be one size, but if he goes out in the cold for a few minutes, it's bigger when he comes in. Shouldn't it be smaller - shrinkage and all that? What's up with this?
