I’m a bisexual male. I’ve been on a drought when it comes to having sex with women so I started having casual sex with men. I’ve always used a condom and none of them ever broke. I checked after each encounter to make sure . I was always the top. I’m now scared to get an hiv test because of symptoms such as on going headaches on and off for about two weeks now and small lymph node in neck seems like it has appeared in chin on right side area. Ive had about 5 or so sex partners. The only unprotected thing I did with some of them was received unprotected oral. Was I exposed to hiv?
