Start using condoms no matter what.
Thanks for your comment. I'm just confused by this. I'm not very sexually active at all, that's why I know exactly the last time I had unproctected, and that was about 15 months ago. my appointment is set for tomorrow. Thanks
No a test will not tell you who had it first. For a male to have it for that long would be very unusual. Most likely she did not get it from you. But you need to be tested and treated.
