I feel really stupid (not to mention slightly uncomfortable) asking this question... but here goes. When I'm bathing my 3 year old son, should I ever pull his foreskin back (assuming he will let me!) and try and clean under it? I have never done this but feel that it might be necessary, as I've twice in the last couple of months found little white marks on his pants which I can only assume is some kind of natural discharge. Hope this question is not beyond the pale..
