What to tell him? He has grown quite large and comes out of the shower usually with an erection which he walks around with. He is a very sincere boy but when I was his age this was something you did not sport about. My wife tells me it is a passing phase but I worry a bit because our younger daughters see him bandying his hardons and I am wondering what this will do to their development. I do not want to stunt his mental development or give him some hangups, in addition to which my wife finds this normal and a passing phase. But still I find it distressing to see him walking around with massive erections as if nothing were. What to do in this situation?
