All the exposures are necessarily infective. We have many couples with regular sex contacts in one of them HIV
positive and the other remain HIV negative for years together. This condition is called sero-discordant couple. Anyway check your blood for HIV with some Rapid or ELISA
test. They will usually become positive within 8-12 weeks time if it is really infective. You already crossed 2 months. So you can get yourself checked and if it is negative you are safe. In case if you are having a positive test then also there are lot of treatment modalities to remain healthy for any long duration. So this is the right time and get checked than thinking the probabilities and chances. You will be free.
