Sharing bed sheets, is it me?

[MakeMineALarge1]

Ok I really don't know if I am being weird here, but I have my sheets on my bed that I share with my husband and my daughter has hers that she shares with her boyfriend.
I bought myself some new bedding last week, I have used it once, washed it etc and now she has put it on her bed!
I don't know why but it makes me uneasy, obviously its washed between uses etc, I can't verbalise it but if makes me uncomfortable.

My partner's step-daughter (what's that in Mumspeak - DP's DSD?) rented out their house for a year while they were working abroad. On her return to her house she confided she couldn't face using the same bed-linen. I sympathised and jokingly said maybe you should burn them, and the mattress of course. She actually considered it! Think she dumped the bed-linen, in the end. And put the mattress in another room. And it was far from fresh bed-linen and new mattresses she was reared!

I wouldn't have thought about it but yes, if my daughter was doing the dirty deed on the sheets I wouldn't want to use them, washed or not.
