When I was younger I was very slutty carefree and slept with quite a few different people, but I wasn't very careful 
. Three years ago I went to my local GUM clinic convinced that I had ended up with something serious and lifelong. They said "no news is good news" and that they wouldn't be contacting me if the results were all clear and I could safely say after 2 weeks that they were all clear. I still rang them after 3 weeks but she just said "well everything's fine if you haven't heard".
Having had encounters with a couple of people in the last 3 years, and now having been seeing someone for the past few months, I still had this niggling in the back of my head that I've caught something. Again I went back to the GUM clinic a week last Monday, and was told that this time the do let everyone know what the results are, and yesterday I had a text to say I was in the clear.
I still am totally paranoid that I have got something. There is nothing wrong that I can tell (i.e. my fanjo hasn't mutated into something resembling something from outer space) but it's just there. I don't know if it's down to all the (rightly so) scaremongering adverts and health promotions out there or linked to my own hangups I have about sex.
Does anyone else have health paranoias?
