Cold after unprotected oral sex

Patient: I had unprotected oral sex 3 days ago. Should I be concerned and worried about possibly contracting some sort of std? I had never performed oral sex before, this was my first time. Although I’ve never performed oral sex before or engaged in intercourse, my partner has had a lot of experience. As of now, I have a minor soar throat and runny nose. It could be a coincidence and a slight case of paranoia considering it’s been raining frequently.
