I mean it is an erect penis. It is in proportion and quite detailed. He didn't intend it for a cock as far as I know - he was just messing about with clay, but the finished model is quite unmistakeably in the shape of a man's genitalia. It has a bell end and everything.
Normally when ds has made a model we varnish it and put it on the windowsill. He is very proud of this model. Wtf am I going to do? I have the health visitor coming round this week and it is not really going to impress her is it.
