Hi, I Have Been Having A Very Weird Thing Happening

Hi, I have been having a very weird thing happening to me. Sometimes at night I wake up to having an orgasm and I'm a virgin and never had a boyfriend yet to let you know. Now sometimes I get really aroused from nothing and I can feel that my body really wants an orgasm and the arousal is intense. My clitoris erects and that whole area is really hot when I'm aroused. What should I do?
