Unknown Bumps on Scrotum and Shaft

I have had these bumps for about 5 years as soon as I hit puberty and started growing pubic hair these smallish pimple-like bumps appeared. It seems like the majority of them are where hair is growing out of the skin, some do not have hair growing through them. They have gotten more numerous over time and almost entirely effect my scrotum and the base of the shaft only. With a few near the end of the shaft (recently). I am still a virgin and am 18 now. If I were to become sexually active I would want to get rid of these bumps if possible, I don't want people to think they're an STD. Sometimes they become irritated and turn red somewhat like a pimple and will start to hurt and itch, I can pop them like a pimple when they are in this state, and they will heal. The others I cannot pop, and they aren't red or itchy. I can go to the doctor if I need to but I am shy and not sure he will know what they are. Should I see my regular doctor, or go to a dermatologist or something? Any solution on making them go away, or am I stuck with them?

HI,
This could be keratosis pilaris.Keratosis pilaris (KP, also follicular keratosis) is a very common genetic follicular condition that is manifested by the appearance of rough bumps on the skin and hence colloquially referred to as "chicken skin" as well as "meat bumps".
Keratosis pilaris occurs as excess keratin, a natural protein in the skin, accumulates within the hair follicles forming hard plugs (process known as hyperkeratinization). Bearing only cosmetic consequence, the condition most often appears as a proliferation of tiny hard bumps that are seldom sore or itchy.Many KP bumps contain an ingrown hair that has coiled.
The condition often improves with age and can even disappear completely in adulthood.
Retin A and medicated lotions containing alpha hydroxy acids or urea may be used to temporarily improve the appearance and texture of affected skin. Also, beta hydroxy acids can help improve the appearance and texture of the afflicted skin.
