Need to be a bit more specific there, and i'm sure you can find what you are looking for elsewhere on the site (http://www.sexinfo101.com/pw_erogenouszones_2.shtml).

That will help, but just go with the flow. Most girls (correct me if im wrong) enjoy having their breasts touched, and can be a pleasurable experience for both the girl and the guy. However, you cant just dive straight in, you need to get the girl in the mood first.
