3 bumps underneath head of penis

Hi, i've had three little bumps underneath the head of my penis ever since i can remember (at least since 15 or 16) before being sexually active.  They don't hurt or cause any discomfort, nor do they appear flesh and wart like.  I've had a hsv 2 test done in the past and it came back negative.  Any thoughts on what these could be doc?

Since the bumps apparently are unchanging for many years, and began before you started having sex, you can be entirely certain they represent no disease.  Perhaps some sort of anatomic variation (prominent Tyson's glands? Sebaceous cysts? Other?)  I cannot make any better guess.  See a health care provider, but in the meantime don't worry about it.
