I Was Intimate With My Girlfriend On Tuesday May 31st.

I was intimate with my girlfriend on Tuesday May 31st. I may have been premature in starting intercourse. As a result, I have small abrasions on my foreskin. It's very irritated and red. Not the actual penis, just the foreskin. One off the abrasions is right at the tip and burns when urinating. It's happened in the past but problem is corrected within 3 days. This is unusual that it has lasted this long. I have used some neosporin and seems to help for a while but result is the same. Very irritated and discomfort. No bleeding and no discharge of any kind. Can you please help me..
