About a week ago I had sex with a man who is 22 years old. I am only 16. I was also drunk at the time. The man kept pressuring me and my friend to drink and he himself only had a couple of beers. I did "consent" to sex and wanted to at the time, but then again I was drunk. Could I bring this to court and get him charged? Would I get in trouble for drinking as well? Please help.
Yes, this man could get in trouble for unlawful intercourse with a minor - a felony (PC 261.5). If it can be shown that you were impaired at the time, it is possible that he could also be charged with rape (PC 261), though since November this would effectively be a "non-violent" offense and subject to potential minimal sentencing if it could be proven to have occurred.
Keep in mind that just drinking does not mean you were too impaired to give consent. You'd have to be pretty clearly drunk and incapable of giving consent for it to be the crime of rape per PC 261. No matter your impairment, sexual intercourse between a 22 year old and a 16 year old minor is potentially felony unlawful intercourse per PC 261.5.
You cannot "bring this to court," but you CAN tell your parents and report it to the police. You should also consider counseling.
