I've had some encounters with a few girls where I did'nt sue protection. I'm 18 now. The 3 girls were all a year or 2 younger than me, and they went out with a few guys each, normal stuff. Reading about aids got me so paranoid and i'm always a hypochondriac. I was at a checkup and my doctor said I looked 100% healthy from looking at me, and doing some checks on my armpits, sides, and neck and stuff. He pressed in those areas to check for swellin and stuff. I went to him because lately the past 2 weeks i've been coughing, nasal congestion, and my stomach wont take much food, and feels acidy when I drink orange juice, also I feel fatigued and have bouts of anxiety(about health) the last time I had an encounter, sexually, would be last summer. I've been completely fine since teh encounters aside from teh norwalk virus I got from a friend once. Am I just paranoid ? My friends and the doc say I am...
