Okay, So I Went Out Saturday Night With A Tampon

Okay, so i went out saturday night with a tampon in...i went home with a guy... i dont remember anything from the night before, i have signs showing that i had sex, and comments made to, but yesterday i felt around and couldnt feel anything so i figured i must of taken it out..... well today, it was there.
