Would he notice or even care?

My boyfriend is staying the night to night for the first time tonight (just sleeping). I am staying the weekend in my college apt dorm. When I got here I realized I have stains on my sheets from that time of the month that did not come out in the wash. I do not have time to wsh them (nor do I like washing them in public washes, I usually take them home to wash). I have a spare set but they are very cheap and rough and uncomfortable, and have been stored under my bed for a year so they are probably musty. Will he notice or even care about the stains? He isn't shallow at all. And the sheets have been washed, they r straight up stains because the sheets are old.
