The risk is lower for other STDs, like
gonorrhea, herpes, or trichomonas, but not zero. Probably there is no realistic risk of either HIV or syphilis in this setting, although these STDs could be higher risk in some settings -- e.g. if either of you is African American, or Latino/a in border areas of the southwest. If you're both over 25, and especially if over 30, the STD risks are really very low.
What to do now?
