Ihave bumps all my labia minora, they don't itch, they don't cause any form of pain, they are under the skin and are whitish? what is it?

Probably normal.: Could be normal anatomy in this area--especially if they are very tiny and don't change over time. You should see your doctor to make sure it isn't anything like hpv warts, an infected or in-grown hair follicle or a clogged duct from a sweat gland.

Fordyce spots: This could be be Fordyce spots which are normal appearing glands along the inner surfaces of the labia minora
