I dont know if it works for girls, but I remember a scene in the movie Raging Bull where Jake La Motta used a pitcher of ice water.
Seriously, it sure is nice to partake in the physical part of a relationship. If someone were to ask me what my favorite hobby was, I would have to say working the secret services. But I also think it is important to go slow and not get into an intimate relationship too soon. But you also dont want to wait too long. I had a girlfriend once who I was best buddies with on a platonic basis for about 8 months. Then when it went to the next level, I realized she was quite frigid and we were incompatible for any long term R because of that. But I was still thankful for the good times we spent together.
