I don't know...fear mabye? Ever since I was 14 (I was molested by a 25 yearold man) I have had this fear of Aids. I used to go to the library and look up all the symptoms of it and (still do) check my body for unusual marks or swollen lymph nodes (still do that too) When I was 16 I got a really bad strep infection that caused thrush of course I cried and cried till I figured out it was the strep. I never have told anyone until now about my fears of this. I thought it would help to do that. But it has'nt. Before my husband was dx with Crohn's they tested him for that and all other STDs and they all cam eback neg and still I worried.
