weirded out..

So I was laying down in my bed for a few minutes and I decided to cover up. When I moved the blanket my vibrator fell out of the covers. When I asked my boyfriend why it was out, he smiled and said "I might have barrowed it."  he took it from me and put it back in my drawer. I'm not sure how I feel about it... I'm a little weirded out because it's my vibe and he just decided to use it when I was working... how would you feel or what would you say..?
