Well, the sore throat you had appeared the morning after the act. This in no way can
be attributed to HIV
ARS infection. This takes a few weeks to develop. HIV
is not a concern, I assure you. You didn't have a risk, SERIOUSLY. The sore throat I'm sure came from just a virus that was going around.
So hard to do but really, try and relax. Take comfort in the fact that you had NO risk with stated activity.
