What are these white bumps on my pen*s?

I get white small ''popups'' around my pen*s head for a while (1-2 years).
but they not disturb me, I'm curious what are they. Maybe I'm sick?

So what are they?
Is it serious?

Small bumps on the pen*s can be a few things. Little white bumps on the shaft of the pen*s that don't hurt and are not red or swollen may be pimples or ingrown hairs. These are common and they're nothing to worry about. Another condition that's normal and no cause for concern is pearly penile papules. These whitish bumps appear on the glans (head) of the pen*s or along the edge of the glans in many guys.

If you are or have been sexually active, bumps on the pen*s may be signs of sexually transmitted diseases (STDs). Painful blisters, bumps, or ulcers may be herpes. Another STD, genital warts (HPV) can show up as bumps on the pen*s. Sometimes these are irregular in shape or even barely seen, and they're not painful. Some other STDs, like syphilis, also can show up as painless ulcers on the pen*s. Although the bumps associated with STDs may not be painful, they could put your health and your partner's health at risk if they are not treated quickly and properly.

Of course, the skin on the pen*s — like the skin anywhere else on a person's body — can get irritated. And it's often hard to distinguish normal bumps from those caused by an STD. So the only way to really know what your bumps are is to be examined by a doctor.

Sorry you maybe have an yeast infection. Thats the kind of infection thats not too serious if you seek medical attention at a early point. Women tends to know if they have an infection earilier than men because of the kind of discharge that they have and the other reason is that it can be seen on the seat of their under wear, but men cant so after the (popup's) as you tend to call it and a very un pleasant smell thats when they sometimes find out.My advise to you is to seek medical help.

my friend had the same things you are describing we got him checked out and they turned out to be genital warts. Sounds horrible but its not that bad, easily treatable.
