I am not here to judge nobody.I am a physician,so age does not matter for me in this regards.
Now looking at history of unprotected sex a year ago,dialy sweats with no other symptoms,it seems least likely that you may be having HIV as it is mostly accompanied with other symptoms too.
Mostly HIV presents with diarrhea or recuurent infections ot weight loss.
Now there is always a possibility that HIV could present with any vague picture and can present with daily sweats too,but it is advisable that we rule out other causes too such as thyroid
problems as increase thryoid hormone can present with daily sweating too,so ask your physician to do thyroid stimulating hormone(TSH) to rule this possibility.
Other possibility could have been malignancy but as you do not have any other symptoms so it is low in our list,but still ask your physician to do a detailed physical exam , complete blood count and look for white blood count and their differentials to rule out this possibility too.
There is high possibility that this could be anxiety,so after ruling all organic causes,we can come to diagnosis of exclusion which is anxiety.
