Impurity

Dear brother i put tissue on private part and in the morning i woke up and found it was damp i check my underwear it was dry as well as my trouser. i change my underwear but not the trouser. After showering i wore the same trouser. Have i done the right thing. because i said to myself that i didnt see any wetness i am fine.

Also i ask that urine equal to 50 pence or inside the palm and you said both or all right both size or different and why must people say it is 50 pence.
