tiny bump

Hi doctor, I recently found a tiny bump half way down on the shaft of my penis.  There is no hair follicles in that area.    
The bump is less than 1 mm in size, no itchiness or tingling felling from it, whether it's touched or not.  It hasn't grown in size in 6 days. When I moved my finger on top of it, it felt like the bump is below the skin, like the skin is moving around it.  Just wondering what that can be, anything STD related?

Hello,
It can be due to folliculitis, cyst or genital wart(caused by HPV infection).

Apply warm compresses,Neosporin ointment and calamine lotion and avoid messing with it.You  can take anti-inflammatory pain killers like ibuprofen or acetaminophen.If the lump persists then it will be best to get it evaluated from a dermatologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.

The tiny bump has been there for 8 days now.  No change in size.  Symptoms are the same, no irritation or itchiness.  I have been examining it daily, and I found out if I stretch the skin, I can barely see some whitish color. I wouldn't say it fill with whitish fluid because it's not swollen.  Just wondering if anyone can give me some advice.  

Also,  some of the people on the web said vinegar has been used by doctor to detect genital warts.  When vinegar is applied to the area, it will turn whitish color.  Is that true? How useful is vinegar in detecting genital warts?

Thanks
