I used to be quite the promiscuous one in my earlier years, and slowly started to change my ways in my mid twenties. I get an anual check up, but i've never been too confident it was thorough enough. I have been in serious relationships for the past few years, and am in one now that I intend to stay in permanently. The problem is that she has only been with one other and I have been very nervous from the beginning about giving her something that I am unaware of ever having. Aside from my yearly checks, I have had no idea of how to know for sure. After reading through some of the forums, I have become very worried that I have given her something. The one known as "trick". I was tested for a burning sensation (i am very unknowledgeable about this stuff) a few years back and given an antibiotic, but turned out that my test was negative. I was told it could have been dehydration. Since my currentgirlfriend and I have been together, I have experienced it again a few more times but not quite as painful. Shortly after, she experienced the same thing. A little while after that, she was having discomfort during sex. And now she is spotting a week and a hlaf early. Please help
