<s>[INST] Hello. Would you be able to inform me as to if i may possibly have an std?I had unprotected oral sex about a month ago. And now i have a slight stinging sensation when i ejaculate. I don't have any burning when i urinate, no discharge or soreness anywhere. She only performed oral sex one time. Do you think this could be an std? I only have one regular partner and the only other encounter i had with anyone else was the oral sex i received on this one occasion from the other female. [/INST] HelloThanks for query.One never gets STD with oral sex ,STD is acquired only through intra vaginal sexual intercourse with infected female .This could be due to Urethritis due to oral sex and will get cured with antibiotics like Cefixime and anti inflammatory drugs like Diclofenac twice daily.Ensure to drink more water.Dr.Patil. </s>
