I Was Recently Diagnosed With Chlamydia. I Am Married And

I was recently diagnosed with Chlamydia. I am married and completely monogamous. My husband finally told me that he went to a strip club and received a nude lap dance and hand job. He swears that's all that happened. He says that she touched her vagina secretions as well as spot on her hand before giving the hand job. I don't believe him at all but just need clarification.
