Talking with SO about STI issues

I’ve just gotten into a new relationship after a month of dating through apps. There were moments of unplanned sex involved, I tried to be careful after my first sexual encounter in this recent adventure put me in a spot where I could not properly protect myself.

I thought I was taking careful measures with the dating scene but there was no way I could have foreseen an STI coming... About two weeks before meeting my SO, I started feeling extremely fatigue, experiencing painful cramping and lower back pain. The first time we had intercourse, he was fully aware that something was going on with my body, and used condoms. The next day as he was about to fly out for a two week vacation, I reluctantly had unprotected sex with him.

While he was away, my condition quickly deteriorated and I let him know of the possibility of an STI. I was really scared, but more so disgusted with myself for letting this happen. I told him that if me telling him this puts him off, he should reconsider our relationship. He reassured me everything was going to be okay and we went on with our relationship.

It’s been about two months into our relationship, and I have finally been diagnosed with trich last week, and just got a second positive test from chlamydia today after a false negative in April.

He’s going to receive treatments on Monday, but I’m really depressed thinking about what he’d think of me now... STI isn’t something you get for sleeping around. It’s chance with new partners who are not aware of what their exposure is.

Every time I have a new partner, I go for a full round of tests. I can’t believe the one time I actually do catch this infection is while I am having a wonderful relationship with the best guy I’ve ever met in my life. He doesn’t seem as bothered by it but it torments me that he might lose feelings for me over this...

I want to sit him down and honestly ask for his thoughts on all this but he’s got so much work that I don’t know how to open the conversation under a calm setting.

What do you sisters think is the best angle to solving this matter? :(
