I tend to get tonsil stones frequently, but I was worried something else was going on. The other day, Friday, I gave oral sex to my new boyfriend. Due to lack of prior communication he finished in my mouth. I did not swollow it, but now, days later, I noticed this white in the back of my throat where the tonsil stones usually are. This time, however, it is not the stones that are balled up and coming out, it is moreof a mucus . Tis the changing season or something else?
