Hi Scare I am not an expert on HIV but I have read a lot, I got this from the body home page, they are big on HIV just as Medhelp. I will post what they wrote about female to male transmission, let say the lady you had sex with was hiv+.
Women are much more likely than men to become infected by an HIV positive heterosexual partner, according to a study released in August, 1997.
Scientists now believe female-to-male transmission is rare. Women were about eight times more likely than men to become infected by their HIV positive partners. The probability of HIV-positive women infecting their male partners with the virus was found to be significantly low.

I hope your testing will be in your favor.
Since your condom broke, you may have been exposed to HIV risk so need to get tested at 3 months post-exposure to get a conclusive result on your HIV status. Circumcision only reduces HIV transmission chance, not eliminates it altogether.
