Your clitoris is the most sensitive part of your genitals - that one spot has more nerve endings than a guy has on his whole penis! Many women, when masturbating, concentrate on their clitoris much more than on the inside of their vagina because it's such a sensitive spot and a great way to reach orgasm.
The fact that you aren't as turned on by fingering yourself as you are by touching your clitoris is typical of most women, and does not mean that intercourse will not be pleasurable for you. However, many women do not have orgasms as a result of intercourse, because intercourse is not the best way to stimulate the clitoris. Most women require some additional stimulation - either from their partner or themselves - in order to climax.
It sounds like you're very in touch with your body. When you begin having intercourse, we hope you and your partner will be able to communicate with each other and find what is pleasurable for each of you. In the meanwhile, from what we can tell your body sounds completely normal.
