Oral sex... worried ?

So there was this guy I really liked , & one thing lead to another & I caught myself giving him head . & it was super unplanned so his dick tasted like piss . I gave him head for like 1 min until I almost threw up from the taste. I feel really embarrassed asking this question, but this is the only place I can ask should I be worried he gave me a disease ? I’m 100% positive he doesn’t have a std or anything but can I catch something from giving someone head if they haven’t showered .
