Where are they - legs? Face? Genitals? What do they look like - are they white, red, do they have a head like a pimple?
Little bumps can be from so many different things - allergic reactions, shaving, dermatitis, etc. The only way to know for sure is to get seen by a doctor.
If it's genital, it could still be any of those things. Genital warts are usually white or pink, and raised. There are a bunch of other things that cause bumps on the penis - pearly penile papules, Fordyce spots - those are totally normal.
Women also have Fordyce spots, and they are totally normal.
If you are concerned, go to the doc. I know it can cause a lot of anxiety, but really, you probably aren't any less nervous just sitting and wondering, right?
