A few days ago, my boyfriend found out he has an STI [1]. He claims he hasn't cheated on me, but we've been together for two years. I went to the doctor and it turns out he passed chlamydia [2] to me. I'm on medication to treat it, but I've been feeling horrible these past couple of days, both physically and mentally. As of now, I just want to focus on taking care of myself and on getting better.

I've confronted him numerous times and he still claims that he hasn't slept with anyone else. The doctors said it could have been dormant for a while, but he claims that masturbating may have caused it. I've never heard of that and quite frankly, don't believe him. He's been a great, trustworthy boyfriend so should I take his word for it or am I just being naive?
