I don't think there's a tag for it.

he's pretty small XD

It's a realistically sized penis. Rare indeed.

My penis gets about 16.9 cm long and something about 2 cm wide when in ready mode. Is that like average or big?
Also, i apoligize if this sounds like bragging.

That's average and something that when put with your last sentence, makes me feel quite sad for the male gender.

Wait, wait! Those measurements are completely of the walls. 2 cm? Where the hell did i get that idea? Its roughly 5-6 cm wide and almost 17 cm long.
