A Vibrating Dildo Cast From Your Own Erect Penis

i broke up with my ex six months ago, and now i'm stuck with albatross in my underwear. He surprised me on my birthday by telling me to close my eyes and he placed an unidentified fallic object in my hands. Upon opening my eyes, i discovered that this object was a vibrating dida cast from his own erect vetus. Now that we have broken up and i am in a new relationship, i would like to return it. Brothers, is there any way on earth to tactfully return my exploit for its manhood?
