I've noticed women complaining about their husbands leaving yellow stains on the sheets, full length of body. It takes awhile to show up on new sheets but after awhile it is definitely there. It also shows up on the pillowcases and seeps into the pillow.

I stopped dating November last year and my new bed from same month hasn't got any stains yet. Will it start turning yellow when I start dating?

Why do sheets turn yellow when a man sleeps in them and how to prevent it?

Edit: There are a lot of assumptions in this thread. This is not only a problem with greasy NVM. Hygienic non-smoking and non-drinking HVM leave stains too, and a clean pyjamas doesn't solve the problem. Yellow shit seeps into the very heart of the mattress. Don't know if it's gravity or dark magic, but I demand an explanation. Any biochemist queens on this sub?
