The oddball mom of eight newborns hasn't had sex for eight years, and vows to go dateless for another 18, according to published reports yesterday. Nadya Suleman, 33, insisted she hasn't been with a man since well before her eldest son, who is 7, was born though in vitro fertilization. "I can't remember the last time I went on a date," Suleman told The Sun newspaper of London, after she was asked when was the last time she had sex. "Boyfriends? I think I'd have to be extremely selfish. I cannot maintain a social life and be a mother."
