My dp has always had a bit of hygiene problem, sometimes dosnt brush his teeth before bed, somethings goes for over a week without a shower but a few times i have been in the bathroom and found skid marks on his boxers which really make me feel ill, I didnt know how to handle it without embarrasing him but then to make matters worse I went to do some washing and there was skid marks on his socks too and my son said he saw his dad wiping his bum with the socks because there was no toilet role.
How do I handle this without causing an argument or am I just over-reacting?
