bump in pubic hair

I had unprotected sex about 2 and a half weeks ago. 8 or 9 days later I noticed a very large bump in the top right of my pubic hair. It was flesh colored and painful if touched by my hand or clothing. 2 or 3 days later it burst and left white thick puss in my underwear. The bump started to flatten and left small open sore and broken dead skin because the bump was huge. Doesn't hurt anymore unless I really apply pressure.  We only did it in one position and where I had the bump never touched her body. Any help would be appreciated.

you need to go and be seen and get a proper exam done. no way for us to know what is going on.
