I had oral sex, and almost anal (but never went in fully and stopped before we continued) and immediately after i have a cold. should i be worried?!?!

Safer Sex: Oral sex is generally considered less risky. You need to understand the importance of risk for STD's and practice safer sex until in a monogamous sexual relationship and possibly even after that until you are certain neither have anything. The cold came from someone a few days before since symptoms do not develop that quickly from a cold.
