I had kissed a girl?

what you did is not exactly proper, there are other ways how to kiss a woman or make her attract to you, and believe me they work much more then this one. Just go to a stationary shop, but the most expensive/beautiful card with a sorry message. Write your message in it and how idiot you feel now that you did so and give it to her, and hope that she forgives you rather then going to the first police station.
