Take this as a learning experience. Don't put yourself in situations like these in the future. Not only did you black out, but you were grinding on another man.

Just imagine if that other man didn't realize how drunk you were and thought you were making a move. You could have slept with him without being aware at the time. This is why people need to be aware of their drinking limit and not place themselves in compromising situations, especially when drugs and alcohol are involved.
