I had unprotected sex with a white women, around 40 years old, and about 7 weeks ago. I am unaware of her HIV status. For the past 3 weeks I have had the following symptoms: diarrhea (usually after eating). Weight loss (I went from about 144 to 134). For a little over a week I had no appetite, and that's when I lost the weight, but since my appetite has came back. I also had a pretty bad headache a few days ago. Also this was the first time I had sex, I'm 19.
