It is really hard to answer you. What are you doing sexually? If you need your clitoris to be engorged to have an orgasm (and that is not unusual or wrong) than your clitoris needs to be paid attention to during sex. This could be by touch- your partner can finger your clitoris, by oral sex with his mouth, tongue or even teeth, or by using a sex toy. If your clitoris is not responding, my best guess is that your clitoris is not getting the attention it needs.
If this doesn't help , tell me more and maybe I can help better.
