In recent blog posts, 44-year-old Sinead O'Connor tells her fans she is at the peak of her sexual prime and ''desperate for sex,'' including anal. The Irish singer says she is in need of a ''a very sweet sex-starved man" who is at least 44, has a job, lives in Ireland, is hairy, isn't named Brian or Nigel, and ''must be blind enough to think I'm gorgeous.''
