in most states I am aware of, it is rape when you are incapable of giving consent due to intoxication so yes, you were probably raped. At the least you were sexually assaulted to some degree. Each state has its' own definitition of the varying degrees of sexual assault. Without you mentioning the state, I have no way of researching what the actual crime could be.

Unless there are witnessess or you have some other proof it will be difficult to prosecute though and the DA may not attempt to prosecute.
