I have white 'dots' / bumps under where hair follicles are...?

I would say they are only small sebaceous cysts which have formed in hair follicles on your s. It is safe to squeeze this white pus type material out of the bumps. I often do this for my wife and it causes no problem. It is important to keep the area clean after squeezing out the pus. Men often get these bumps on their and testicles. Sweat causes them.
