What Causes Painless Red Bump On The Perineum?

I am a 25 yr old male and I noticed today a single tiny painless bump right on my perineum. It is in the center Between my anus and scotum and is barely noticed by just looking. When I stretch the skin around it the perineum flattens but the bump can be felt. It looks like it could be nothing but a minor skin irritation. when I touch it I do not remember feeling a very small bump there before. It does not look like a pimple, wart, ingrown hair, cyst, nor sore. There is no pus and it does not itch. There is no other bumps like this one on my body. I shaven the area earlier in the week and I have been sexually active but it s not located on the anus or scrotum. There was no color it when i first noticed but after picking and touching it became a little red. I am leaving it alone for now hoping it goes away eventually or at least does not get bigger nor spread.
