This was a sexual assault. In my mind, there is no question about that. This person used you. If you were passed out while they fingered and fondled you, it was NOT a mutual activity. You were NOT consenting for that to happen. When you passed out, you were in a vulnerable position, unable to say yes or no to anything. For a person to take advantage of that is WRONG. I don't care if you were passed out and lying there completely naked, this did not give anyone a right to hurt you. Please do not fall into the trap of blaming yourself for what happened. Yes, you made choices that increased your risk, but even so you still did NOT deserve what happened to you, and it was still abuse. I agree with inkblot and ozzie that seeing a counselor would be a good idea for you.
