Is it normal to regularly jizz in your socks?

Personally I don't go about jizzing in my socks every night and day and moring and every other imaginable time.

But

A friend of mine has admitted and evidence has been proudly displayed (in the form of a loaded sock) of his practice of wacking off in to a sock which he had been wearing all day. This is something which occurs quite often and it has gotten to the stage where he says his c*ck smells like his feet.

He also has to wash a seperate "load load" when doing his washing.

Is this normal? Surely it is not the most hygenic thing is he likely to get some sort of infestation downs below from his practices????

Normal or not? Comments greatly encouraged thanks
