My boyfriend thinks that it is not normal to not be able to have an orgasm through stimulation of my clitoris yet I can easily orgasm through intercourse. 

My clitoris becomes very sensitive but not in an orgasmic way.  Is this normal or are there things to do to help increase the chances of an orgasm through stimulation of the clitoris?

Here we go again with that word normal. There are over six billion people on this planet and thank God they are all different. We should learn to celebrate our differences rather than all be striving to be exactly the same.

The important thing for anyone is to have the ability to have orgasms. Orgasms bring needed sexual release and are very pleasurable. Assuming that no one has to be injured in order for someone to have an orgasm (I’m thinking of people like pedophiles, for example) then however a person has orgasms does not matter at all. There are millions, maybe billions of women who would love to have orgasms during intercourse who can’t. Your clitoris seems to be very sensitive, which is why you can have orgasms from the sensations of intercourse alone, and can’t have them when your clitoris is stimulated directly because it is uncomfortable for you. So please tell your boyfriend that he is a very lucky man to have you, not because of how you have orgasms, but because of everything about you, no matter where your qualities fall on some bell curve of normality.
