Second Life

Hi--I wonder if anyone has been to second life that I know. I hear about technology people spending time in second life but I have not had good experiences there. Is it the wave of the future or just a game that will come and go? I see some fun that could be had there but I have had to walk away from many men who do not know that kissing someone as soon as they meet you is not acceptable (at least not in the South). I can understand why teenagers and kids are not allowed in second life. It seems to be a fantasy world kinda like the Sims. Has anyone been to second life and had a really good experience.
