Both my boyfriend and I are completely clean, STD and any other infection free. for obvious context, more than not we will do oral before general intercourse. I noticed this morning that I have several little white pockets of what looks like pus in the back of my throat. I had this issue with a boyfriend I had about a year ago as well, and when I got tested I turned out to be clean then as well.

Is it possible that I might be allergic to precum? It may also be a reaction to semen, but more likely as precum.

Direction for research, tips, or advice would all be appreciated. Thank you
