Shit, I have another thing to add. If you choose to take something that will be mind/mood altering and you know that you get sexually provocative then take steps to make sure you don't get taken advantage of. Stay with a group or a sober buddy.
Take drinking and driving for an exsample-you go to a party and you know that you are going to get drunk. You make sure that you have a taxi or a sober driver. You don't get to drink and drive that one time and kill someone. You don't get to use the excuse of "I blacked out".
That being said a person should never take advantage of someone that has blacked out. You know that isn't the real sober person. Also WTF? Are you that bad of a fuck that you don't want to be remembered?
