This is not an STD. What you describe is about as good a description of folliculitis as I have heard. Folliculitis occurs when the pores in your skin get plugged. This allows that
normalNormal saline flush bacteria that are present on just about every-one's skin to grow and cause what is essentially a pimple. Some of these just appear as red bumps which may or may not be tender while others go on to actually form pimples. In your case, you can even see a hair coming out of, or nearby the bump- (this too is typical of folliculitis).
Sometimes when clients try to "pop" folliculitis lesions there is a small amount of residual scarring when remains behind. This scarring can take weeks of even months to resolve. The best way to prevent and even treat folliculitis, should it recur, is to use
gentleGentle laxative abrasion when washing the genital area such as that which occurs by using a wash cloth or a loofah sponge gently to make sure that your pores stay open.
There is nothing to worry about and this is not something that you can transmit to others. EWH
