Question marks.

I need help. I recently noticed a bump on my public mound area right next to where my thigh and it meets. The bump now looks sorta like a blister, but it doesn't really hurt. Being who I am , I start messing with it. I popped it and squeezed all the pus out of it. Sounds just as gross as it was. But it's odd to me that it looks like a blister, but I read online that it could just be an infected hair falicule from an ingrown hair? Does that sound right?
