I've been dating a really nice guy for just over a year, with a few months separation inbetween. 2 weeks ago I went to the sexual health clinic to have my injection and also had a routine check up. I got the results back about a week ago and they were negative, this morning I had a phone call from the clinic saying that they misplaced one of my tests and I have tested positive for an std and to go in to get treatment.
Obviously I know I need to tell the guy I'm sleeping with and will be doing so this evening, as I've already told him I need to see him. But how do i even start that conversation? I've never had an std before and I know that I have most definitely contracted it from him, as my previous sexual partner was over 2 years ago and I have been tested twice since then. Once after my ex and once when I started seeing new guy and we decided not to use condoms anymore, both were negative.
