This deoesnt belong in the Masturbation section and also it said that is was normal in the part below the picture. So I wouldnt worry about it.
These are the perennially-worried-about sebaceous glands. You have these glands all over your body. They produce sebum, which is a white greasy gunk that acts as a natural moisturiser for the skin, keeping it supple. They mostly discharge into hair follicles, and are usually buried under the skin so you can't see them, even when they get bigger, as they do, during puberty. However, the skin on the genitalia is thinner, and so they often become visible there at puberty, and people worry unnecessarily. They are normal.
