An hour ago I had a casual encounter with a guy that I see occasionally for... well... a "booty call". We always use protection for penetration, but I don't typically worry about it when giving him head. Anyway, I was giving him head and he unexpectedly came down my throat so I went ahead and swallowed it. About 10 minutes ago while sitting at my computer, I was clearing my throat and coughed up some chunky white stuff. It was a little off-white, (not liquidy or gooey at all, it was solid and a little crumbly) and smelled HORRIBLE (almost made me throw up)! The smell is still on my fingers from examining it in my hand, and I'm absolutely disgusted (and a little concerned), but I don't want to tell him and freak him out or make him insecure if there's nothing wrong.
Is this ever normal? Could this be attributed to a sexually transmitted infection? Should I get a throat culture soon and tell him to get tested (if so, when)? Should I just wait to see if I get any symptoms?
Thanks!
