I think I corrupted my friend
Why do you think you corrupted your friend?
I kissed them; kissing is one of the first things you do when becoming sexually active.
If your friend was fine with being kissed I don't think you corrupted them. But if you coerced or manipulated them into a sexual situation, you should apologize. It is never ok to push people sexually further than they are comfortable with.
LOL. I got them drunk.
that wasn't a nice thing to do. You should not use others simply for your own ends. You should try to be more respectful to them and let them make their own decisions.
