can i...?

my bf and i only had oral sex. never been prior sexual active. parents clean. no hiv, hsv transmission (mom has hsv 1, i dont have it) can i get any any stds/stis from him?? we are each other's ABSOLUTE FIRSTS. blood test clean. my tonsils look weird abd have some white on them but they arent irritating me or anything and they feel perfectly normal. am i worrying too much? theres like no chance right..?
