Do I have herpes or boil?? Need opinion *picture included*

about 1 week ago, this bump appeared after shaving & also having unprotected sex. I have been with the same and only sex partner for two years, but we are not exclusive. I was tested for herpes in January, but I've obviously had unprotected sex since. I tried popping the bump and a tiny dot of white came out, but then it got irritated and grew to be bigger. It occasionally itches, but otherwise I forget it's there. I am prone to folliculitis but I'm still worried it would be herpes, etc. Any advice will help!image

it may be a boil try but a hot towel and ointment on it i have this kind image you can get the adult kind i just work at a baby store so it was convenient to get this one works great.
