Welcome to the Forum. while you do not ask a specific question, my sense is that you want to know what this is (and is not) and whether your current warm, tingling sensations are related or not.  My thoughts:

1.  This is not a history which suggests an STI.  What you describe could well be folliculitis (which can occur even in areas which are not cover with hair) or a dermal/sebaceous cyst. The rapidity with which the lesion appeared and grew is not suggestive of HPV or other STIs, not is the response to removal as you describe.  

2.  I suspect that your current symptoms are unrelated.  On occasion when person begin to look for symptoms or signs at any part of the body they tend to become aware of what are normal sensations which we more typically overlook.  When persons concentrate on a specific area, the sensations they typically experience are itching.  Again, this is not a symptom typical of STI.  When STI symptoms occur, they do not come and go but tend to appear and stay there or progress.

I hope these comments are helpful. If there are any follow-up questions or concerns, please do not hesitate to use your up to two additional follow-up questions to seek clarification.  EWH
