I recently had an erotic massage with a happy ending, where sexual intercourse is typically not part of the service. However, during a simulation of intercourse using hands, I briefly felt that my penis may have entered the vagina for a short time. I stopped immediately. It has been 5 days since the event. I have experienced symptoms such as fatigue, muscle aches, chills, discomfort when swallowing, and a sensation of low-grade fever (though my measured temperature is normal). My penis appears normal, with no pain or visible change. I feel quite anxious about the possibility of HIV or others STIs.

My questions are: 1. Based on this type of exposure, is there a realistic risk of HIV transmission? 2. Are my current symptoms consistent with early HIV infection, or more likely related to anxiety? 3. Do you recommend any testing, if so, when would be appropriate? 4. What about the risk of other STIs? Thank you.
