While many couples get tested together before starting a sexual relationship, it isn't necessarily an error not to do so or to insist a partner be tested. In absence of symptoms, I would not have thought it necessary for you to be tested at this time. In any case, the tests you had are highly reliable, in any and all labs. You indeed can be certain you have none of the infections for which you were tested.

That doesn't prove your partner doesn't have a transmissible STI; all STIs are transmitted inefficiently, and it is possible to have multiple exposures without catching anything. If your partner is a typical male who has had multiple male partners himself, it is reasonable for him to be tested for common STIs from time to time. If I were in your situation, I would discuss my own testing and ask (not insist) that your partner also be tested. Probably he will understand and comply -- but that's between the two of you. Maybe you'll even find he has exactly the same concerns you did! 

I hope these comments are helpful. Let me know if anything isn't clear.

That being said, my real concern would be chlamydia or gonorrhea since it is often asymptomatic. After 6 months of weekly sex would an infection more than likely be passed on? Or can chlamydia and gonorrhea remain asymptotic for 6 months? 

I also had a gyno appt after my negative tests and was told everything looked normal down there. 

Men who have sex only with women have far lower STI rates than gay/bi men, and absence of symptoms also is a good indicator, although not perfect. So in view of both your negative test resuls and normal gyn exam, I don't see his being tested is a high priority.

And your negative gonorrhea/chlamydia tests are good evidence he doesn't have either one. Although not transmitted with every sexual episode, having had somewhere around 25 exposures (weekly for 25 weeks), almost certainly you would have tested positive if he had either of them. I really don't think you need to be worried at all.

I sense a relationship problem here. That's not our expertise and I have no advice about it, except that you might consider having a sensitive, caring discussion with your partner about your fears. In that context, perhaps he would agree to being tested. But in all honesty, your concerns seem way overblown. In any case, that completes the two follow-up exchanges included with each question and so ends this thread. I hope it has been helpful.
