Sometimes, it's just a matter of technique.
Oral sex is wonderful... when there's some "finger" action added.
You need to have a conversation with him-outside the bedroom-to discover if it is either. Find out if he was given negative feedback by a past partner. Or if he is turned off by the smell, taste or the bushel of hair. (Unfortunately, if this is a cultural thing - some cultures just don't think it's right - then you're probably fighting a losing battle.)
When you hear his concerns, don't judge and don't get upset. If you do, it will only make him feel worse about the situation.
Then tell him gently that oral sex is something very important to your sexual enjoyment. Together figure out how you can work around what he has told you.
I think that nothing is really wrong with you, there are many women who do not like or prefer oral sex. It is highly individual. I love giving oral sex but I have met more women who did not like the idea of receiving oral and they did not allow me to do it. In fact, as for my sexual history, there were more anti-oral ladies than pro-oral, so you are definitely not alone in this. It´s your preference and there is no need to compare to others.
Nothing is wrong with you, and to be honest most men or women are lousy at sex particularly oral sex because they nevaer learned to listen and watch their partners body. Sex is a skill that has to be learned and is most often practiced by amateurs.
