This is a situation I was put into. Except we had along distance affair.
Iwas being druged and raped. I started to feel ill, in july, by september I had a full out break. She would have known when she had a full out break. I was lucky, that year my partner and I only saw each other once, and it was in the carring stage, before the out break happened. For a female, the shame, the guilt, the anger that someome gave it to her, she may have been raped, that is why she is being vage about it.
The sad news, you may have it, it usually takes 3mths for a full out break. But if you are one of these guys who does very little 4 play, and has a shower, straight after sex, you may have been lucky and advoided it. But these actions alsomake the girl feel cheap, so you cant win either way.
Just go get tested to make sure, the doctor will do it easy since you had a partner with it at the time.
Don't be like mine, I was worry sick, that I might have given it to him, he would not go to the doctor, until I lost my tempter and said prove to me you didn't give it to me.
I was so happy, when he came back cleared.
