@fmeekins It’s strange for me is that she’s immediately accusing. Like if she hasn’t been tested why wouldn’t she first assume something like a yeast infection?
@fmeekins IMO it’s a red flag unless there is some clear or defining medical concern or a previously condition that has returned. Has she acted different or taking extra time with things at all lately to where it’s possible she cheated? UTI’s can be common when new sexual partners are introduced so unless you can completely rule that out don’t put it past her.
@fmeekins Hoping it’s just something minor and insignificant but always have to consider everything in this day and age. You both should take a full STI/STD panel and rule out any concerns especially if you have no symptoms and have been clear.
@fmeekins One or both of you could have/had HPV which isn't easily or regularly tested for in men. Either of you could have had it for some time with it remaining dormant for some time before becoming active. If it is HPV, the only thing you have to rely on is trusting your partner in that they say.
Edit: there's no point speculating, she should just go get tested.
@fmeekins My guy it seems like there are quite a few boxes you should check before anyone here will be able to help you. Let us know what happens though.
