Big O?

So um, I'm 18 years old and a virgin, i do not plan to lose my v card any time soon but i do have needs... unfortunatly no matter how i try or what i try i have never had an orgasm tho i would get maybe close... i dont know im not sure how it feels and i just feel uncomfortable cause i want to but... i just can't. I want to know if that is odd and/or any suggesyions to help, thank you
