Sorry about the break up. The fact that this was a regular person you were in a relationship with is good as that sure cuts down on the risk. You'd probably know if he had hiv. But testing now would make sense to make sure. Unfortunately, yes, you know the drill. AT 28 days or beyond, you can take a 4th generation DUO test for an accurate result. Get one and put it behind you. HIV does not get diagnosed by symptoms nor would sweating at night be associated. Just take the test and move on.
As to your new relationship, you asked a while ago and we gave you the risks of HIV transmission. I'll repeat them again for you. The risks of getting HIV are to have unprotected vaginal sex, unprotected anal sex or share IV drug needles. Using condoms is a no risk situation. Giving or receiving oral is a no risk situation. People do not get HIV from oral sex (as we told you last time you posted about this on the forum). Saliva and air inactivate the virus.
