I am a 23 year old college male. I have been seeing a girl this term who I like very much. However, she has had more sex partners than I am comfortable with. I am carefull sexually, and use condoms religiously,and don't sleep around.She has been tested for STDs reguarly, and has promised me she has never had anything,or never had any symptoms of anything. Sometimes I notice a white substance between her vaginal lips.At first, I took it for tiny bits of wadded up toliet paper,but when I wiped it away, it had a creamy/chalky texture to it.There was no smell, and she didn't notice it.Sometimes there is nothing there, sometimes it a bit more noticable.(she takes oral acne and birth control every day)We slept togeter once, using a condom. A little after 3 weeks(and the same time I had finished 2 strong rounds of anitbiotics), I developed pimples on me shoulders, legs, and a tiny whitehead in the upper part of my pubic hair. It didn't hurt, and drained pus and blood, like the other pimples. We both read a lot of stuff on the internet, which scared us silly about STD's.We both got checked and tested.Our tests were all neg, our examinations turned up nothing, and her PAP was completely normal.We were both told by different docs we had nothing to worry about.The whitehead healed like a pimple.I got a 2nd doctor to look at me, and he said the same thing. About a week later, I got a red streak in both creases of my legs, which burned and itched.I saw another doc, and he said folliculits, and gave me more strong antibiotics. The medicine and anitbacterial soap did nothing to it, but it faded to pink and only itched when I sweated or walked longs ways.Over the holiday break, I saw a urologist, who really checked me over, and said I have nothing to worry about regarding STD's(he said my streaks looked fungal).Over this period I developed oral thrush, and the corners of my lips got red and split. I saw a dermatologist, who said angular cheletis(?), and gave me Protopic for my lips and a mouth wash. When I got back to school, the spot behind my testicle got red and itched and burned, and then spead to my lower buttocks and around my anus. I've put Lotramin on the areas for about a week now, which helps the irratation, but hasn't really changed the rash(the new areas have now turned a more pinkish color).I saw a STD specialist, who said no STD causes these symptoms, and said I have no STD. Today I got a small pink bump on my lip(not near the skin). It looks like a small tastebud on your tounge, and doesn't hurt. Its about 1 mm big, and can only be seen when I stretch my lips.My question- is this all caused by yeast or another fungus? My worry is this could be HPV, which I've read can be invisible.I've had nothing on my testicles or penis. Could I have a genital wort on my lip? How can I keep the rash from spreading and how should I treat it? Its been about 2 1/2 months since we slept together. I am worried about HPV, even though several docs say I don'have it.
