Something similar happened to me. I used to live in an apartment with a friend. As far as I know he never has had a relationship with someone or been intimate with anyone. I was waiting on a package once from Amazon and one came in the mail. I assumed it was mine but when I opened it, there was just this huge bottle of lube.

I texted my friend and said "I put your package in your room from Amazon." To this day he still swears that he didnt prefer it from Amazon but we had a good laugh about it
