If you had unprotected sex but the man did not ejaculate can you still contract hiv?

Yes, still possible: Ejaculation in the vagina isn't necessary to transmit HIV, although it probably raises the chances. OTOH, if a male has HIV, average transmission is only 1 in 1,000 unprotected vaginal sex exposures. And if your partner isn't at special risk (gay, IV drug use, etc) the odds are low he has HIV. But don't take chances; get tested for HIV and STDs. And use condoms for new or unsafe partners!
