On DH's side, so not so bad 
Only just noticed now as I picked his pyjamas up to wash and noticed they were wet but his bed was suspiciously dry. He had got into bed with DH for a cuddle whilst I got up with DS2, and left a little surprise.
How do I get it out??? The stain is the size of a dinner plate, and pretty well soaked in by now. Was looking forward to an early night with my book, not so tempting now
