First, in response to the discussion before this reply (below), if a condom breaks of course it is obvious when you withdraw and see the penis was uncovered--and usually the rupture is felt at the moment it occurs.
You were not at risk and do not need testing for HIV or any other STD. Remember that even without a condom, the risk of female to male HIV transmission for any single episode of vaginal sex averages 1 chance in 2,000 if the woman is infected. Since the odds are low your partner was infected (HIV remains rare in most sexually active women in the US and industrialized countries) and condoms are nearly 100% protective, the chance you caught HIV is zero for practical purposes.
