Many feel the same way initially. They have some issue they feel will not be approved. This includes girls as well as boys. Generally girls are worse about some issue than boys. So most likely your gf feels the same way about something.
The two things you described is not something that is bad about any body part. Actually the blood dots may be useful later in pleasing a female. The coloration will probably not be noticed.
If you are concerned, you will probably continue to be until you find that it is accepted the way that it is, which is what will happen when you get to the right time with the right person.
