Probably Yes.

Thanks for the question.

You may have given him Chlamydia. You should get treated and be tested for other sexually transmitted diseases, and consider telling him to also be tested. If you need to remain anonymous, you can tell the people at the state health department his name when they contact you, and they will do the notification. You should also let your doctor know, if your diagnosis wasn't made by him or her. And use what protection you can!
I hope you will be treated and do well.
