He gave me oral for about 3 minutes and that was it. I cleared my genital warts two months before that with no recurrences. I am worried about his risk of oral HPV and then the chances of him passing that onto his wife via oral to her. 

Secondly I had a one night stand unprotected. Again , warts cleared a couple of months prior. Obviously this is more risky but what would you say the chances of passing this on is? And then him passing onto wife? Do transmission risks decrease with no visible warts and two months time passed?

Thank you very much
