having sex with two differnt guy. Sometimes same day and some time alternative day.but everyone is HIV negative. Is there is any chance for us to get HIV +
If you are 100% sure that everyone is HIV negative the risk is none. But take into account that there is a window period where someone can test negative and in fact be positive.
The testing guidelines for HIV are to be initially tested at 3 weeks post exposure and then again at 90 days. As long as there are no other exposures happened during this time frame than the results are conclusive.
Be well and stay safe, Shannon
