What precautions would you put in place if you were going to meet someone off the internet ?

On impulse, I once hooked up with another man on the internet just so that I could experience same-sex "intimacy" and satisfy my curiosity. Naturally, given the nature of the encounter, it took place in a quiet location, and I wasn't about to tell any friends what I was going to do. Fortunately, nothing untoward happened (other than the performance of the deed we met up to do!), but in retrospect it was unnecessarily risky. Unfortunately, it's too easy to get caught up in the heat of the moment and not think things through.
