Eminem's ex-wife Kim Mathers has said the rapper is "not very well endowed". Mathers made the remarks during an interview with US radio station WKQI, in which she also said she wants to "vomit in my mouth" whenever she's near him. Mathers also offered advice to future partner's of the rapper who want to enjoy a good sex life with him. "If you're going to have sex with Marshall, make sure that you have a little blue pill. Otherwise it does not work," she said (WKQI).
