hmmm this is a good one, Im 16 and I've was able to make my ex orgasm like all the time through fingering, you need some general foreplay to get them really revved up and wet. You can ask her, but I always thought it was better cos I felt like I knew what I was doing etc. It was more general massaging but you definately needed to explore the canal, she definately found it entertaining. It's kinda in there and up.
Other girls said I was pretty good at it too,

Hope this helps.
