More a WWYD, but I suppose the AIBU is whether I would be unreasonable to say something about this to the person concerned.
I have a male friend whom I've known a long time. We have had had an intermittent FWB benefit arrangement in the past but I stopped this because of his personal hygiene and because I found him very selfish in bed. However I do like him as a friend and we meet fairly frequently as we're both single and live nearby.
Every time I see this chap, without fail, he has visibly greasy hair. I find this really quite repulsive. He clearly still wants to continue our former arrangement and, when we were on holiday recently, was quite put out that I didn't want to share a hotel room (i.e. bed) with him.
On the third day of the trip I could actually smell his unwashed hair, even when we were outside. He doesn't have noticeable BO, although when we've slept together I haven't been exactly blown away by his high levels of cleanliness and I noticed that he wore the same trousers and jumper for the whole three days we were away.
My reasons for saying something would be a) because I find it both revolting and somewhat insulting that he can't be arsed to wash himself properly when he has a visitor and b) because I know that he would like to find a partner (or even just have sex occasionally) and can't help thinking that this would put most women off. I also don't want to say something in irritation when he inevitably once again makes noises about us having sex.
So, if IANBU, how should I tackle this?
