Hi, I'm Sixteen Years Old. I've Always Thought Myself To

Hi, I'm sixteen years old. I've always thought myself to be a healthy teenage girl when it came to my vag. I've been masturbating for quite a while and within the last couple months have had sex for the first time. I've taken a closer look downstairs, and have noticed some weird qualities in the skin. It has underneath the skin clusters of small white bumps. Kind of look like pimples except cannot be popped. Also it tends to be veiny and the skin is just not what I had imagined to look like. I'm not sure if this is normal or what?
