The odds a woman like your partner has HIV
is zero or close to it. Being in New
York could elevate the chance she is infected, since heterosexually transmitted HIV is more common than in most other cities -- especially if she is African American. But even then, it is unlikely she has it. And if she were infected, the odds of catching HIV from only a single episode of vaginal sex are very low, probably on the order of 1 chance in 2,000; and oral sex is virtually zero risk.
